In addition to the Banana War God, Li Junhui, this racquet also had early endorsements from the Grand Slam champion Zhao Yunlei and the “Sweetheart” Wang Xinling (just kidding).
Before discussing the feel, let’s talk about ultra-light racquets (5U and below). Generally, ultra-light racquets face two main issues:
1.Leverage: Due to the light weight, if the balance point is very low, the leverage effect is minimal. This makes it necessary to apply extra effort to achieve distance even on high clears, which further impacts offensive performance. To achieve leverage, a head-heavy design can be used to increase the balance point. Alternatively, leveraging the shaft’s deformation can help, which means the shaft should not be too stiff and must have good elasticity. A high balance point combined with a less stiff shaft is ideal.
2.Stability During Impact: Head-heavy racquets with a soft shaft may suffer from excessive frame wobble during powerful shots, leading to reduced stability and precision. To address this, it’s essential to balance the shaft’s hardness, elasticity, and torsional rigidity (referred to as the shaft’s bending stiffness).
Energy 70I
Pure Breakwind Frame
5U weight
Balance Point is not low
Most importantly, the shaft is long and soft
These factors directly contribute to instability in the hitting feel.
Overall Feel
The most noticeable initial impressions are the light weight and the prominent Breakwind feel. It is positioned as a “sugar water speed racquet,” which means it’s easy to use and visually appealing. The description “sugar water speed racquet” encapsulates its primary characteristics.
Negative Experiences
From my personal experience, there are some aspects I found uncomfortable. The intended characteristics of being “light” and “fast” should be the main features of this racquet. However, the long and soft shaft results in poor elasticity. The shaft feels quite stiff, which affects the force transmission and slows down shot speed. The swing speed isn’t slow, but the shot feels less crisp. (I used it with 29-pound N68 strings, which are relatively elastic, somewhat compensating, but it still felt less direct.)
A fellow player in a discussion group described it as “long power,” which means the long and soft shaft delays the power transmission, unlike the quick response of a short shaft. This long and soft shaft is a disadvantage in the mid-court. In the backcourt, high clears are easier with more leverage, but smashes feel weak due to the soft shaft and Breakwind frame.
Did Li Junhui Really Use This Racquet for Smashing?
It’s possible that Li Junhui’s exceptional skills could be the reason for the powerful smashes, rather than the racquet’s strength. Another plausible explanation is that the version he used was different from the retail version available to the public. Li Junhui mentioned in interviews that he prefers light racquets, and there are reports of a 3U version of the Energy 70I used by him.
However, these speculations aside, the retail version we can purchase is a relatively “sugar water” light-speed racquet.
Just the fact that it’s the “Zhao Yunlei signature racquet” already gives it enough of an
After the Energy series was introduced, this legendary racquet naturally came under the Turbocharge banner. The current test is of a used racquet, and although I haven’t played with it extensively, it perfectly matches my stereotypical impression of high-end Li Ning racquets from that era. Not in a derogatory way, not at all.
Specifications: 5UG6, stripped down, current total weight 86.0g, balance point 306mm, shaft length 220mm, moderate hardness, Energy Reversal Breakwind Frame, 76-hole string bed, 8-2 o’clock string groove, 32-pound warranty, strung at 25-27 pounds with BG65TI.
Many might have bought this racquet for its cute pink design. The racquet head is white, with cyan-green on the wings, and the frame lower part is entirely pink, creating a layered and stylish appearance. The Energy 70I seems to be the first Li Ning racquet with such a pink design, representing a transformation from the “tomato and egg” era. However, it doesn’t quite fit Zhao Yunlei’s image, haha. Moreover, the sharp Breakwind Frame combined with the painting process of that time makes it prone to chipping, which becomes quite noticeable. The racquet I have has several visible chips.
I wonder if any female players bought it for its looks but found it unsuitable for them, similar to the fate of the Speed 12F. Even I felt that this 5U racquet was unexpectedly heavy, which perfectly fits my stereotypical view of older Li Ning 5U racquets — ultra-light but with high swing weight, like a meteor hammer.
The head-heavy design indeed provides a noticeable leverage effect. During warm-up for high-clear shots, the 70I felt comfortable to use. With a long shaft, the deformation threshold is low, and the racquet face and sweet spot are exceptionally large. The slightly wider frame compared to the Blade series makes it easier to adapt to high swing speeds, allowing for accurate high-arcing backcourt shots.
It might be my illusion, but I feel the 70I doesn’t have as much “sugar” as the 3UN72. Although the shaft hardness between the two seems not drastically different, the 70I is rated lower in hardness according to equipment information.
In flat drives, while not extremely agile, it surprisingly has power. Due to the strong head-heavy feeling, the 70I experiences a slight delay during the transition from setting up to swinging, forcing users to adjust their grip position to improve continuity. However, during continuous drives, the 70I shows a noticeable driving force, utilizing the shaft’s elasticity to produce powerful and aggressive shots. The large sweet spot makes it easy to handle, and despite being somewhat unskilled, I found it challenging to handle shots to the side, but everything else was manageable.
The 70I has an extremely strong smash capability. Even for many amateur male players, the feedback and shot quality during attacks are excellent. Although many criticize older Li Ning racquets for their soft shafts, the elasticity is quite good. Additionally, the high balance point adds to the weight of the head during smashes. Zhao Yunlei’s comprehensive skill level complements this racquet well — I retract my earlier comment.
Moreover, I think this racquet is quite sufficient for many singles scenarios. The large racquet face and solid feel boost confidence in net play. Its defensive adaptability is also impressive; the large face and high elasticity make it easy to handle defensive shots, although controlling the shuttle to the backcourt requires some effort to avoid going out.
However, it’s not without flaws. The racquet still has issues with direction control during long shots. Whether it’s due to the Breakwind Frame’s inherent disadvantage or the soft shaft leading to head wobble, the 70I’s performance in controlling long-shot placement isn’t as precise, lacking in hardness and directness.
Overall, I see this as a direct competitor to the Speed 12F, and after using it, I feel a sense of wanting more.
Among Li Ning’s mid-range and low-end models, the Wind Blade series stands out in terms of popularity. Although the Energy series also has a few enthusiasts, it cannot compare to the Wind Blade series in terms of visibility. As for the Wind Storm series, despite high ratings from equipment reviews, it remains less prominent, largely due to its association with the older AirStream lineage.
Among these, the Wind Blade 6000 fares better, while the 5000 and 4000 models are less well-received. I want to see if the latter models have any real merit.
Specifications: 3UG5, stripped down, current total weight 92g, balance point 305mm, shaft length 215mm, moderately soft tuning, box-shaped frame, 72-hole string bed, 9-3 o’clock string groove, 30-pound warranty, strung at 26 pounds with N68.
The mid-range frame features only one pair of wind holes, which is quite distinctive. The current model comes in black, purple-red, indigo, and emerald green color scheme. I feel like I’ve used a racquet with this color scheme before, possibly similar to the 7000B, though I haven’t used that model. The design is youthful and vibrant, but only to a limited extent. Generally, Li Ning’s paint quality is reliable, but unfortunately, the previous owner didn’t take good care of it.
Don’t be intimidated by the balance point and specifications; upon first use, you’ll find that the Wind Blade 5000 is a very user-friendly racquet. It’s head-heavy, with a long shaft and relatively soft hardness, making it feel easy to handle despite the slightly heavy swing weight. Unlike the holding sensation due to a soft frame, the ball stays on the Wind Blade 5000 longer primarily due to the shaft, though its elasticity is adequate. The head-heavy design enhances directional accuracy, and with brief practice, you can control the ball’s placement accurately near the back line during high-clear shots.
Despite the heavy swing weight, it doesn’t feel cumbersome, similar to the Wind Storm 9000. This advantage is likely due to the wind holes.
If you don’t mind a softer shaft, this racquet offers a very satisfying feel. My recent experience showed that I need some “sugar” in my game. The difference in feel between entry-level and high-end racquets had previously made it difficult to adjust, but I’ve found that the Wind Blade 5000 provides a pleasant hitting experience.
The head-heavy design causes the head to drop, and the shaft’s deformation is easily managed. The combination of elasticity and head weight avoids a sluggish hitting feel. The feedback isn’t direct, but the heavy smash quality is still good, reminiscent of old Li Ning’s solid but soft hitting feel with a large sweet spot, making it easy to handle. The downside of the heavy swing weight is somewhat mitigated by the lower power requirement.
However, continuous defensive play in doubles can be challenging. While it can handle individual smashes effectively, sustained defensive play becomes more difficult as the shaft and head begin to wobble, and the swing weight remains a factor. In fast-paced rallies, the racquet’s softness and head-heavy design may hinder quick reactions and adaptability.
In conclusion, I initially treated it as a smaller version of the Wind Storm 9000. It’s a versatile mid-range racquet suitable for both singles and doubles. While the Wind Blade 500 is popular, I find that other mid-range models offer similar benefits without the higher price associated with popularity.
C for Combat is generally regarded as a mid-range Li-Ning product emphasizing attacking play, regardless of its release sequence. The Wind Storm 4000C, launched in 2017 alongside the Wind Storm 4000, is designed with an attacking mindset. Above it in the lineup is the Wind Storm 5000, which has a strong attacking feel.
1.The release time was early, and 2. Being positioned between two numerical models, rackets in such a “gap” often suffer from unclear positioning and can create marketing dilemmas.
Specifications:
Weight: 3UG5
No base grip
Total Weight (used condition): 88.81g
Balance Point: 311mm
Shaft Length: 218mm
Stiffness: Moderate
Frame: Box frame
Wind Tunnel: 4 and 8 o’clock
String Bed: 72-hole
String Groove: 9-3 o’clock
Warranty: 30 pounds
Recommended String Tension: 25-26 lbs BG65TI
As expected from its release time, the Wind Storm 4000C has only a color difference from the Wind Storm 4000, changing from gold to red to emphasize aggression. The racket’s details and technological applications don’t require further elaboration; it probably reused the same shaft as the 4000. However, the length has been restored to the standard 675mm, making it visually more appealing.
This racket should be a typical 3U head-heavy model. In the balanced Wind Storm series, treating the 4000C as an attacking racket is reasonable. Although the 4000C initially feels heavy in the hand, it becomes lighter after warming up, similar to the Wind Storm 9000, which feels lighter in use despite appearing heavy. Although labeled as 3U, I suspect the empty weight is just around 85g, making it feel closer to the Wind Storm 4000B compared to the Wind Storm 5000.
Unlike the Wind Storm 5000, the 4000C has slightly higher stiffness, so the sweet spot sensation experienced with the Wind Storm 5000 is somewhat reduced. During high-clear warm-ups, the 4000C feels less tactile, with good elasticity, friendly driving, a consistent sweet spot, smooth power generation, and satisfactory placement. However, it doesn’t produce a satisfying smash.
Despite the C suffix indicating a more attack-oriented model in the series, the 4000C feels quite balanced, similar to the Wind Blade 600C. The 600C’s shaft is stiffer and more decisive in shot-making. Compared to the Wind Blade 300C, the 4000C is lighter, making it hard to determine which has better attacking efficiency.
I initially had several perfect smashes go into the net, possibly due to low string tension or the racket’s torsional resistance issues, with the former being more likely.
In fast drives and blocks, the 4000C doesn’t exhibit the same delay as the Wind Storm 4000, and its weight doesn’t compromise agility. In fast-paced rallies, as long as the racket is positioned correctly, it maintains good continuity, though the long shaft still affects recovery speed. During the test, I wasn’t too concerned about opponents’ backcourt shots and could focus on maintaining continuity at the net.
Defensively, the racket handles opponents’ smashes effectively but is less efficient for backhand returns, affected by the shaft’s elasticity and weight.
I initially thought it might be more suited for singles, especially with BG65TI strings, but found it a bit challenging for men’s singles; it might be easier for women. I’m surprised by the discrepancy between my experience and the reviews, which align more with my pre-test expectations. Maybe my game has improved?
Overall, this isn’t a difficult racket for beginners, and the C suffix shouldn’t be intimidating. Among the three Wind Storm models, I am most satisfied with the Wind Storm 4000B. Thus ends my review of the Wind Storm 4000 series.
Feeling spontaneous and starting something, only to find that once you begin, you can’t go back—this happens often. Just like how, after trying the Wind Storm 4000B and Wind Blade 300 and feeling pleased, I got the idea to explore the entire series for performance differences, leading to a new small goal.
One must accept the possibility of making mistakes, having poor performance, and the reality of struggling financially while pursuing these goals.
Specifications:
Weight: 4UG5
No base grip
Total Weight (used condition): 93.0g
Balance Point: 300mm
Length: 670mm
Shaft Length: 210mm
Stiffness: Moderate
Frame: Box frame

Recommended String Tension: 25-26 lbs VBS70P
This is also a second-hand racket, and mid-range rackets typically show more wear, as users are less likely to treat them as carefully as high-end models. Without a suffix, this racket is from the earliest release of the series (2017). The black base paint and yellow stickers, with minimal other decorations, give it a dull appearance, quite different from the later 4000B (2019) style. The shaft has minor changes, but the total length is only 670mm, which is shorter compared to mainstream models, possibly inspired by the 88S to adapt to doubles play.
Though labeled as 4U, the racket feels more like a 3U model in terms of swing. Low-end models typically have only two wind tunnels, which don’t significantly improve swing speed. I agree with the notion that “making a hole is not as good as making the frame thinner.” The short shaft increases the difficulty of driving, and the shaft’s normal performance feels wooden. The head has some weight, but the string bed’s sweet spot is consistently large, making the entry level manageable. However, the enjoyment of hitting is not very noticeable.
In terms of feel, it remains within the balanced racket series comparable to the Wind Storm. The ball control feels substantial, likely due to the VBS70P string.
The racket is responsive and performs well in terms of torsion resistance and forgiveness. The feel for small net shots is solid. Changing to a thicker and stiffer string like the BG80 could further improve the feel. Defensively, it’s average, with stable returns and decent flexibility, but the touch for net play and the feel for soft shots aren’t very clear, which is not my preferred style.
If the Wind Storm 9000 is a balanced racket scoring 85-90 points in various aspects, I would rate the Wind Storm 4000 around 60 points.
The 4000 does not offer significant advantages compared to the 4000B. For example, the shorter shaft’s potential for explosive power doesn’t improve the racket’s overall continuity or endurance. The lack of sugar in the smash feeling doesn’t present more issues, but this subtle difference makes the user more restrained in the backcourt, focusing on controlling the shot to create better attacking opportunities rather than just blindly smashing. Analyzing it this way, the Wind Storm 4000 does help in making shot decisions more rationally, though it’s not as satisfying.
Regarding opponent control, the 4000 excels in directional accuracy and feel, particularly for backcourt drop shots and smashes, making it quite handy. In long-distance shots like clears, high clears, and flat drives, despite some lack of communication with the racket, the placement of shots is satisfactory.
However, in fast drives and blocks, the slightly head-heavy weight and sluggish string bed response negate the flexibility benefits of the 4U weight and shorter length. It doesn’t feel agile, and in situations like chasing backcourt shots, it mainly performs simple blocks, with less effectiveness in powerful re-drops.
So, it’s not particularly outstanding. However, in line with the principle of unity and opposition, its imperfections can refine the approach to doubles play, making it useful as a training tool.
In terms of technology, it features multiple composite carbon fiber reinforcement systems, mechanical optimization frame, aerodynamic cross-section system, superconductive nano, hot-melt glue, return elastic twist angle, and high rigidity thin shaft. Yet, in other aspects, it remains a mid-range balanced racket from a major brand.
Some things are hard to admit are good, such as Tenga’s suction or Chun Shui Tang’s skin care; some things are hard to admit are bad, such as my own lack of skill in badminton and the shortcomings of some renowned rackets.
I’ve never been fond of using discontinued old rackets, especially those from brands L and Y. They’re often talked about more for their hype than their actual performance, and their prices can vary widely—skyrocketing for rackets endorsed by stars while those without endorsements often languish in obscurity. Additionally, for someone like me who has a high demand for modern feel, these overly classical or even outdated rackets usually end up being a bad investment. This was fully demonstrated with the N553. I believe I’ve done it justice by updating the N553 review.
Specifications:
Weight: 3UG5
No base color
Total Weight (used condition): 95.0g
Balance Point: 320mm
Shaft Length: 210mm
Stiffness: On the stiffer side
Frame: Box frame

Though the manufacturing technology at the time wasn’t advanced, old Li-Ning rackets had a “classic” appeal, and the paint quality was already top-notch. The N553 can be considered a “Purple Gold Sword,” with a blend of blue and purple colors on the frame and gold paint, creating a layered effect with pearlescent shine. The shaft is mainly gold, reflecting the aesthetic preferences of the era and its flagship status in the Air Stream series. As the predecessor to the Wind Storm series, the wind tunnels were a standout feature. Although it also boasts six wind tunnels like the 9000I, it uniquely places two of them at the head, which may not be seen again.
Of course, there has always been discussion about the impact of wind tunnels on frame structure, especially at the head. I suspect that Li-Ning’s approach at the time was quite simplistic—since the wind tunnel could cause breakage, why not make the structure weaker to accommodate it? Thus, I believe the racket’s heavy swing weight is largely due to additional material at the head. Although the wind tunnels were intended to reduce air resistance and increase swing speed, the 553’s swing weight is excessively high, making the swing speed unsatisfactory.
Indeed, when I saw some players commenting that it is Li-Ning’s greatest weapon to date, I expected this situation.
Undoubtedly, this racket requires good physical condition and power to be effectively used. While it offers substantial power in slow-paced shots, the sweet spot’s explosive power isn’t very focused, and the shaft’s elasticity is quite poor by today’s standards. Officially, the shaft is described as soft, but it actually feels quite stiff, making it challenging for me to use. I had to force myself to adapt over a week, and only used it in mixed doubles matches where my skill level was not very high.
Heavy means strong, and this straightforward, rough approach does offer benefits in solid feel for small ball control. The net play quality stabilizes easily, and after specific training, it can produce very close net shots.
As for downward shots, the N553 feels too wooden to me, lacking the drive sensation. When given an opportunity for a powerful smash, it feels like swinging a hammer to pound the ground—emotionless and unable to connect well with the ball. Sometimes the slow swing speed makes accuracy difficult, further forcing me to move quickly for better positioning. There might have been a couple of times when I smashed through the opponent’s defense from the back court, but those were situations where the opponent’s clear was poorly placed, and no movement was needed. Ignoring the limitations of the racket in long-term play and focusing only on its maximum potential for smashes is not a rational approach.
Surprisingly, I actually prefer using it for overhead shots. It is indeed heavy, and beginners might risk injury due to improper wrist action, but the strong downward feel of the N553 makes the shuttlecock’s placement sharp and precise, thus improving shot quality.
Handling defensive shots and flat drives is another matter. The extreme swing weight leaves me struggling, and unlike other rackets that might compensate for performance and wind resistance, the N553 relies entirely on the user’s skill.
I find it hard to use and feel that for non-collectors, there’s no need to acquire this racket due to its many limitations. Of course, it might be like “luosifen”—loved by those who appreciate it and avoided by those who don’t.
“Good-looking exteriors are everywhere, but interesting souls are rare.” This phrase reflects a sentiment that while the latter part is undeniable, I just like beautiful things.
For many beginners selecting a racket, looks aren’t enough; it also needs to be from a reputable brand. Before improving their skills, they often rely on equipment to make a good impression. Ideally, if the racket is also easy to use, durable, and versatile, that would be perfect.
Wanting it all might seem a bit unrealistic. The result of such unrealistic expectations is often like my own experience: spending over four hundred on a low-end racket that didn’t meet expectations.
However, after a productive weekend, I think I might actually have a viable option…

Does Li-Ning like the color red? Obviously, their logo is set against a red background, not to mention the color schemes from their first wave of N55 series. While the Wind Storm 4000B is a mid-range model, it also features a bold red design, reminiscent of the Energy 80 that many players find visually appealing. Aside from the color similarity, the racket inherits the high-quality paint Li-Ning is known for. The paint is delicate, refined, and has a metallic feel, with good durability. Apart from the golden stickers, the frame has a subtle dark pattern that you might want to appreciate up close.
The 3U weight might deter some players, but if you want a reputable brand, good looks, and a racket that’s both powerful and fast, you have to be realistic. Despite its 3U weight, the Wind Storm series is designed for control, and for the 4000B model, the 293mm balance point is very user-friendly. It feels solid in hand without being hindered by excessive swing weight. The 72-hole string bed ensures a large sweet spot. While the swing speed isn’t outstanding, the two wind tunnels provide smoothness, which is sufficient.
Try hitting a few high clears, and if you’re a male player over 14, if you don’t manage to get the shuttle to the baseline with the correct technique, consider it a loss. The response of the shuttle on the string bed isn’t extremely crisp but has a noticeable dwell time, indicating that the shaft’s stiffness is not high. However, the thick shaft suggests it shares the common issue with many Li-Ning rackets of that era: a wooden feel.
Let’s break it down: the B suffix denotes a more balanced racket in the series. Honestly, it reminds me of the feel I had with the Wind Blade 900B, though the wind resistance and swing weight aren’t particularly low, and the swing speed isn’t high. It feels quite nimble and stable for flat drives and blocks, making it suitable for mixed doubles players who can effectively pressure opponents with their backhand.
The racket’s somewhat sticky string bed also helps with close net shots and high-point smashes, making it crucial for shifting between offense and defense. After adapting to the 4000B, I found myself able to play effective low net shots and even challenge myself with high-to-low net transitions. Some players might find it a bit heavy, but in my experience, the 4000B handles defense well, allowing for effective returns and powerful smashes.
I know you like powerful smashes. Responsibly speaking, it is the most comfortable and efficient racket for smashes among all the rackets I tested on the day of the review. Compared to the Xiao Gui Zhan, it has smaller forward and backward swings; compared to the Speed 98K, it has better directional control; and compared to the NF800, it’s easier to drive. I’m not saying it’s better than the other three, but once you get it to the right height, the Wind Storm 4000B does deliver, with a solid feel and effective smashes that opponents find hard to return. The only discomfort is that the shuttle’s trajectory is flatter compared to other rackets, possibly due to its balanced design. However, adjusting to this is not impossible. The Wind Tunnel 5000 might be stronger in downward pressure, but it’s less commonly used.
Here’s a tip: after a couple of powerful smashes to intimidate your opponent, a well-executed flat high shot or drop can be even more effective.
I understand that many beginners prefer to use rackets from the big three brands even if they don’t offer the best value or quality, as the brand logo gives them confidence. If the racket also looks great, that’s a bonus. And if it performs well, that’s perfect. According to my recommendation, it’s worth the extra investment. If not, consider the 4000B and make your choice.
I have tried flagship models from the three major brands last year, and the only one I haven’t tested is the former flagship from the ‘Red Factory’. I didn’t expect it to be the Wind Storm 9000i.
The reason I’ve been slow to write this is that I don’t know how to approach it. The ‘Red Factory’ has always been quite stubborn about 5U rackets, especially when trying to balance strong attacking power. This often results in a high balance point and the use of the best mid-shaft available at the time, which can lead to coordination issues with the racket.
Although the Wind Blade 900i provided me with a great experience, the 9000i did not.
Specifications: 5UG6, with a base, total weight in used condition is 89.91g, balance point 320mm, shaft length 210mm, medium stiffness, box frame, 72-hole string bed, full string groove, warranty 30 pounds, string tension 25-27lbs XB63.
The racket has been on the market for a year, and with the overwhelming negative reviews calling it a “hammer,” the 9000i increasingly feels like Lei Zhenzi’s two hammers. Its black base paint and cyan-purple stickers have become the 9000i’s hallmark. As a flagship model, it features many details, including frame edge embellishments, inner frame decorations, a matte finish, gold lettering, and a bright red Li-Ning logo on the T-joint, adding a touch of mysterious prestige. It looks good and is memorable, a strong suit of the ‘Red Factory’. But believe me, the more stickers it has, the more prone it is to defects.
While many criticize this head-heavy 5U racket setup as overly stubborn, I find it not surprising after using rackets like the 900i, Dragon Tooth, and VTFB. The slightly stiffer shaft and head-heavy feel provide a noticeable power assist, with a “solid” hitting feedback, making it somewhat powerful. Under this setup, the shaft-driven feel is noticeable, and the elasticity is apparent. For high clear shots, many players might adapt to it.
The key issue is how much this setup enhances attacking power and how well it balances swing speed and maneuverability.
Regarding the latter, the oversized swing weight requires more space for the swinging action, making it disadvantageous in fast exchanges, especially in doubles where quick blocking is needed. I don’t know how Yuta Watanabe managed to achieve results with the 9000i. Despite its light weight and the rear swing speed not being slow, it often results in frame hits when reacting quickly or intercepting shots. Additionally, during the swing, the 9000i feels like it “can’t stop” during the deceleration phase, with noticeable frame wobbling affecting continuity. Fortunately, the 210mm long handle can help alleviate this issue by raising the grip position.
Regarding the former, the racket has excellent downward pressure. When hitting from a high point, you can clearly feel the frame smashing the shuttle down, creating a low and sharp trajectory. This results in impressive performance in drop shots and cuts, even without focusing on absolute shuttle speed. However, the lightweight design doesn’t easily compensate for the high-weight frame, and in strong attacks, there’s a feeling of insufficient energy transfer to break through the opponent’s defense. But maintaining pressure with the 9000i requires less effort to achieve effective control, which is convenient and energy-efficient, as long as patience is maintained.
The racket excels in touch and control. Its weight within the 5U range provides a solid feel, surpassing many 4U rackets, and its handling allows for very stable net play. Backcourt lifts and slices continue the excellent downward pressure performance, offering high forgiveness and often producing high-quality net shots. As for passive shot handling and defense, while this racket is extreme, it performs adequately in these areas, neither exceptionally good nor bad.
The prevalence of counterfeit versions of this racket makes me hesitant to recommend it. For players interested in the 9000i, there is a high risk. Personally, I find the Wind Storm 9000 much more usable. As mentioned earlier, any feature of the 9000i is also available in the 9000. I don’t understand why this 5U racket has to handle tasks that a 3U racket can naturally manage, and whether players who struggle with a 3U racket can fully utilize the performance of this 5U racket.
As a flagship model from Li-Ning’s mid-generation lineup, it stands out not only for its impressive offensive capabilities within the Wind Storm 9000 series but also for accompanying Zheng Siwei through his remarkable journey. Its popularity and reputation align well with my initial understanding of the racket.
Despite its significant presence and stable price, which has prevented me from completing my trial of it, I have hesitated to borrow it from friends due to its cost and potential inconvenience.
Specifications: 3UG6, without base towel grip, total weight in use 93.86g, balance point 310mm, shaft length 210mm, moderate stiffness, box frame, 72-hole string bed, 9-3 o’clock string groove, warranty up to 32 lbs, strung with 26-28 lbs BS720.
The racket’s visual style is striking, with its color selection—deep blue, azure, and crimson—evoking a strong sense of national style. It reminds me of the carefully restored glaze on ancient artifacts, offering high recognition. Some players have mentioned that this design resembles the style of the AT900T from the past but with a brighter touch, which is indeed outside my area of expertise. However, due to its distinctive look, the racket has unfortunately become a frequent target for counterfeiting.
Although it is well-known that this is a 3U offensive-oriented racket, my initial experience with it did not cause much pressure. Undoubtedly, it has a slightly higher swing weight than the 9000, but overall, it still falls within the balanced racket category. If it were reduced to a 4U specification with its current weight distribution, it would not differ significantly from the Tactic 6000 in terms of empty racket feel.
The shaft is not very stiff, and its quality is similar to its counterparts. It offers a clear feel of using leverage when handling active shots and makes it easy to drive and experience the deformation of the 9000C shaft. The feedback from the shot is also similar to the 9000, perhaps even a bit more forgiving, making it quite user-friendly. The current box frame also shows good torsional resistance and performs well in directional control, with good performance in trying to keep long shots within the small corner grid.
It is said that wind tunnel technology improves swing speed. While previous experiments by Pang Hu have controlled variables, I need not investigate whether the wind tunnel or the box frame with the same projected area is better. At least in doubles play, with the racket in my hands in a mid-to-high state on that day, flat drives and blocks can still create a fast-paced exchange. Although the increased swing weight affects its agility, the longer grip effectively avoids excessive torque.
However, the feel of this racket is not as typical or aggressive. Unlike the current trend of “touch and go,” the 9000C has a more noticeable holding feel. But this is not an excuse; after all, Zheng Siwei has moved from the 9000C to the Double-Edged 10LT and now to the Bow 11P, and with the rumored preference for BG65 strings, it is clear that the racket’s characteristics are mainly to match the user’s preferences rather than specific scenarios.
On the offensive side, the 9000C feels somewhat “conventional.” The racket delivers energy to the shuttlecock through both gravity and elasticity, with little difference in proportions. As one of the best-performing mid-shaft rackets from Li-Ning at the time, its performance now seems slightly outdated. Whether by design or not, among the 9000 series, the Wind Blade is indeed significantly more aggressive than the Wind Storm, providing more confidence in execution.
The 9000C does have a slightly higher pressing feel compared to the 9000. The deformation of the shaft during a powerful smash is not as pronounced as in the 9000, providing more resistance and a feeling of the whip-like motion of the racket head. With harder strings, it should produce a shot power that closely reflects the input force. It is not as difficult to smash with, and both the pressing and power feel reach a certain level of aggressiveness. However, to create absolute threats, it still largely depends on the user and maintaining continuity.
Although it is a C-suffix product, I have not seen any players around me who immediately experienced the heavy-hitting or continuous pressing characteristics after switching to the 9000C. The essence of the 9000C in the market remains a fairly conventional, balanced racket with some offensive features. After using the 4 and 9 versions of the Wind Storm, I personally do not find the 9000C to have extraordinary qualities. Moreover, its series-specific holding feel gives me more confidence in net play and rear court flicks and pushes, leading to a slightly better impression in controlling the rhythm of play.
Based on this understanding, after using all four siblings of the Wind Storm 9000 series, I will probably miss the days spent with the 9000 more.
The “Windstorm” series can also be understood as “wind tunnel.” The frame design of the Windstorm series rackets is an improvement upon the fluid box-type frame, which has been proven over many years in the market. The lower part of the frame is slightly thickened to enhance shot stability, while four air ducts have been added to reduce wind resistance during swings. The principle behind these ducts is similar to the spoilers on race cars and airplanes, guiding airflow behind the fast-moving object to reduce negative pressure at the rear, thus decreasing resistance and enhancing aerodynamic stability.
In simple terms, the Windstorm series frame is an upgraded version of the classic box frame, providing excellent shot stability.
This release of the Windstorm 9000 series includes three models. The Windstorm 9000, focusing on all-round performance, is endorsed by Shi Yuqi, a rising star in China’s men’s singles team. The Windstorm 9000C (Combat) emphasizes offense and is endorsed by mixed doubles specialist Zheng Siwei. The Windstorm 9000D (Drive) focuses on speed and is endorsed by Li Junhui, one half of the “Twin Towers” doubles team. Shi Yuqi is known for his stable and comprehensive playing style. Zheng Siwei’s powerful and fast-paced smashes and drop shots from the backcourt often catch opponents off guard. As a doubles player, Li Junhui demands high flexibility and speed in drives and blocks, and the release of the Windstorm 9000D should allow him to retire his flashy pink racket.
Design
Li-Ning’s racket designs are well known for their durability and appearance, far exceeding the industry average. However, this time, Li-Ning doesn’t just win in terms of aesthetics; the relationship between the design and the racket’s characteristics is equally important.
The Windstorm 9000 features a color scheme of champagne gold and ivory white, with a subdued and restrained overall style. This design complements the all-around performance of the racket and also aligns with Shi Yuqi’s calm demeanor on the court. The Windstorm 9000C, on the other hand, sports a striking combination of deep blue, sky blue, and crimson, giving it a visually impactful look that matches Zheng Siwei’s aggressive and energetic playing style. The Windstorm 9000D predominantly uses fluorescent yellow with accents of green, giving it a flashy and bold appearance—perfectly suited for Li Junhui!
Specifications
The Windstorm 9000 has an unstrung weight of 86g with a balance point of 305mm. The Windstorm 9000C weighs 88g with a balance point of 298mm, while the Windstorm 9000D weighs 84g and has a balance point of 314mm. All models use the thinner S1 handle.
Experience
In hand, the Windstorm 9000 feels slightly lighter than the Windstorm 9000C. Both rackets have similar shaft stiffness, but the Windstorm 9000C has a firmer feel and is noticeably heavier overall. The Windstorm 9000D is completely different, feeling much lighter due to its head-heavy balance. The shaft’s flex during smashes is more pronounced, somewhat similar to the pink Energy 70i, but there are still significant differences in terms of stability, swing speed, and overall weight.
AERONAUT 9000
The Windstorm 900 is a racket with excellent shot direction control. It feels neither as heavy and stable as the Windstorm 8000 nor as crisp and agile as the Windstorm 7000. Instead, the Windstorm 900 feels like a blend of the two, or somewhere in between. The frame stiffness is medium, slightly leaning towards stiff, and the hitting sensation is crisp without being overly rigid. Among Li-Ning rackets, the last model that gave me such a comfortable hitting experience was the Windblade 900. Compared to the Windblade 900, the Windstorm 900 offers better shot stability, although the Windblade 900 still surpasses it in swing speed and precision attacks.
The balance between forgiveness and power feedback determines both shot direction control and racket handling. Rackets with a high degree of forgiveness, like the Windstorm 8000, often have a softer hitting feel. However, because of this softness, the power feedback may not be as direct. In actual use, this can lead to situations where applying 4.8 or 5.2 force yields almost the same results, which greatly reduces error rates but limits players seeking precise control. Conversely, rackets with very clear power feedback tend to have low forgiveness, offering precision at the cost of higher error rates.
The Windstorm 900 strikes an excellent balance between forgiveness and power feedback, providing a comfortable control experience.
One drawback is the 210mm long handle, resulting in a shorter shaft compared to the Windstorm 8000. Rackets with long handles and short shafts generally offer stiffer feedback and faster response, but they perform worse in terms of power transmission during smashes compared to long-shaft, short-handle rackets (those who have used the Windblade 900B/N904 will understand). Therefore, in terms of power smashes, the Windstorm 8000 still holds the advantage. Fortunately, the Windstorm 900’s medium shaft stiffness ensures that, while it’s not a completely easy-to-use racket, it doesn’t require too much time to get accustomed to.
Control is the biggest feature of the Windstorm 900. As an all-rounder racket, the Windstorm 900 also performs well in midcourt rallies and backcourt attacks. In particular, its performance in midcourt flat drives is exceptional, though not as nimble as the Windstorm 7000. The Windstorm 7000 offers faster and more direct flat drives, while the Windstorm 900 feels more comfortable to use. In backcourt attacks, the Windstorm 900 lacks the heavy downward pressure of the Windstorm 8000 and doesn’t have that same explosive power. However, due to its lighter overall weight and higher stiffness compared to the Windstorm 8000, the Windstorm 900 excels in fast-paced attacks.
Based on the Windstorm 9000, Li-Ning has fine-tuned the weight distribution and stiffness parameters to create the attack-focused Windstorm 9000C and the drive-focused Windstorm 9000D.
AERONAUT 9000C
The Windstorm 9000C has a feel very similar to the Windstorm 9000, but with an overall heavier weight, offering a more stable smash, though it can be a bit demanding in defense. The Windstorm 9000D, however, differs significantly from the 9000, with more weight focused in the racket head and a lower overall weight, making it noticeably easier and more flexible to swing, with greater shaft deformation during play.
Apart from the increase in overall weight, the Windstorm 9000C also has a stiffer racket face compared to the 9000. This results in the 9000C sacrificing some comfort for enhanced offense, akin to a vehicle’s “sport mode”—seeking more intensity at the cost of comfort. When compared to the more attack-oriented Windstorm 8000, the 9000C offers a more direct and firm smashing experience. While the Windstorm 8000 feels like a powerful, charged-up strike, the 9000C’s smash resembles swinging a sharp blade. Fans of Bao’s powerful, charged smashes may prefer the 8000, but those who enjoy the fast-paced smashes and slices of Zheng Siwei would find the 9000C a great option.
AERONAUT 9000D
The differences between the Windstorm 9000D and the Windstorm 9000 remind me of the comparison between the N7i and N7. Both models reduce overall weight and increase balance point compared to the originals. The Windstorm 9000D is an easy-to-use racket, being head-heavy yet light overall, with significant shaft flexibility, making it easy to generate power. In doubles play, the 9000D excels in agility during drives and defense. While it may lack the quickness of the Windstorm 7000, it offers more comfort. This reflects Li-Ning’s interpretation of “Drive”—not simply speed, but agile maneuverability, which, in my opinion, refers to nimbleness. Therefore, models ending in “D” tend to have a lower entry barrier.
The Windstorm 9000D also has a stiffer racket face than the 9000. Coupled with its greater flexibility, the 9000D sacrifices some control. When compared to the speed-focused WindBlade 900, the 9000D’s head-heavy design allows for better leveraged smashes, though it lacks the comfortable wrapping feel of the racket face. Personally, I find the WindBlade 900 more comfortable, while the 9000D might be better suited for players with less strength or those who like the Windstorm 7000i but want a softer shaft, or players who enjoy the N7i but find it too light.
Choosing a Racket
The Windstorm 9000 perfectly embodies the core control attributes of the Windstorm series, while the 9000D and 9000C build on this with performance tweaks. The 9000C is closer to the 9000, but with a higher overall weight, making it suitable for powerful, offense-oriented players. The 9000D, on the other hand, is quite different from the 9000, resembling more a softer-shafted Windstorm 7000i with a length of 675mm, or a heavier version of the N7i with a box frame. It is ideal for doubles players or those with less strength.
String Pairing
All three rackets were strung with Li-Ning No.1 string at 26 lbs on the mains and 28 lbs on the crosses. Based on my experience, both the 9000C and 9000D have stiffer racket faces than the 9000, so pairing them with softer strings can enhance the wrapping feel on the shuttle. Given the wear on strings during offensive play, Li-Ning No.7 strings might be a good choice for the 9000C. Meanwhile, the 9000D, which emphasizes drives and doubles play, pairs well with the crisp-sounding Li-Ning No.1 string. For the all-around Windstorm 9000, the equally versatile Li-Ning No.5 string is a viable option.
