NS7000, this racket is designed for middle and senior amateurs. Using 8mm thick rod, the shaft is very elastic, the racket head is designed to break the wind, and the ISO medium-sized racket face is very good for defense. The horizontal shift ability is lower than NS8000, MP- 100, etc. Because the balance point is moderate, it is easy to drive and it is easier to pull the backcourt ball. Compared with Ti- 10 and MP- 100, the killing power is slightly insufficient. Suitable for ball control players. This shot was selected by Gao Ling, the world champion of mixed doubles of the national team.
NS8000, this racket is a very popular one in the nano series at present. At present, the sales volume even exceeds the latest NS-9000. The racket frame 10, the 2 o'clock position and the top of the racket shaft are filled with nano-materials C60 (Flaren). 7mm thin rod, excellent explosive power. Instead of the traditional pipe blowing technology, the racket frame is more stable and the landing point is very accurate when hitting the ball. Adopt one-way threading hole design, the racket is more uniform and durable. Because of its excellent elasticity, it is easier to pull the ball. The balanced design makes it easy for this racket to handle the ball in front of the net. When used in doubles, the horizontal draw speed of NS8000 is faster than that of NS7000 ... Although it is a lightweight design, the offensive ability of NS8000 is only lower than MP- 100 in the coordinates of YONEX racket. This racket is more popular with amateurs than MP- 100 because of its light head and strong continuous attack ability, and its sales volume is very large.
NS9000, the latest heavy weapon. The racket head is obviously heavier than NS8000. The appearance of 9000 drove MP- 100 off the throne of attacking the king. There are two kinds of S/X, which correspond to the hardness of hard and superhard bars respectively. The 8mm thick handle is lengthened, so it really takes some effort to use NS9000 well. The manufacturing method of foam molding is also adopted. The new position of the threading hole makes the sweet area of the racket move up slightly. The use of elastic TI greatly improves the stability and elasticity of the racket frame. For more details about this shooting, please refer to the article "Experience of using NS-9000" written by steven_gu in this forum.
The weight of rackets varies. The weight range of ordinary rackets is generally 80-95g. Like the size unit of the handle, different manufacturers have their own definitions of the weight unit, but the most popular one is the U system used by YONEX. U = 95- 100g，2U = 90-94g，3U = 85-89g，4U = 80-84g，5U = 79-75g。 Generally, commonly used rackets are basically 2U-4U, and those under 79g are generally called super rackets, which are mainly designed for women or have special functions. Generally, those weighing more than 95 grams are metal rackets, which are mainly aimed at people who play badminton as a means of fitness and don't want to spend too much money on equipment.
The weight of the racket determines the swing speed. Using the same swing force, a lighter racket can produce a higher swing speed. Simply put, the lighter the racket, the more flexible it is to use. But the lighter the racket, the better, because the lighter the racket, the more unstable it is, and it needs more strength to keep the track. A heavier racket can bring more kinetic energy when swinging and more potential energy when hitting the ball. This is also the reason why many offensive racket heads are heavier. The following is the evaluation report of YONEX NS9900 badminton racket:
Move like a butterfly and sting like a bee.
Translation of YONEX 9900 evaluation report
First impression:
I haven't received many samples of "Evil Empire" recently (this guy's stuff belongs to YY company), but when they said they would send it, they did. When I opened the latest batch of samples, a racket caught my eye deeply, and I couldn't wait to try it. Like a child who received a Christmas or birthday present, I curiously and carefully opened the plastic film package on the racket.
I can't help thinking, this must be the latest NS9000 series I have learned before. The logo of "NanoSpeed9900" on the racket handle and the racket handle confirmed my excitement. At least I have toys to play with.
I will remember my previous impression of NS 9000X/S. At first, I didn't like their color scheme, but in the end, you will like it more and more. Perhaps this color painting makes the sales of NS9000 bleak and has a so-called "futuristic" appearance, but I will say that NS9900 looks much better than its predecessors.
After using AT900 and AT700 for a period of time, I decided to use NS9000 before writing the evaluation to better adapt to the sense of weight balance of NS9900.
It feels very comfortable when holding the racket, just like using a real high-end racket. The weight of this light header is balanced before and after, which is a bit top-heavy.
Make an impression:
The racket is quite easy to pull, and the vertical and horizontal deformation of the racket is not big when it is pulled at 30 kg. It feels pretty solid. According to unofficial reports, this racket can theoretically withstand 38 pounds of tension. So I think NS9900 has improved its robustness.
Preparatory activities:
I like the hardness of 9.9K when hitting the ball, and it feels between hard and extra hard. Maybe it's because 9.9K is a new camera and everything is so fresh. Probably because of the design of the racquet frame, compared with 9KX and 9KS, the 9.9K swing feels more relaxed. (? Swing wise is something I don't know much about. After all, I don't know much about technical terms. After the first few beats, I really felt a little shocked. However, this does not affect the control of the ball and good feel. It's easy to draw the bottom line, so I don't have to hit the ball. On the whole, killing the ball seems a bit fierce, but the horizontal pull still needs some strength. The racket head swings faster.
On stage:
I like the way it runs when I swing 9.9K. Compared with other ns series beats, I don't feel much procrastination when 9.9K cuts the sky. Even if you shoot your head, you can feel the accuracy and feel when you hit the ball. You can hit the ball anywhere on the court effortlessly. When the ball is dropped and the net is handled, the signal transmitted by the racket frame to my brain is so clear. But I'm not too satisfied with the draw. This shot requires me to make greater efforts to generate the motivation to return. In any case, 9.9K is very flexible and light, even in doubles. I am very satisfied with the overall performance of beat. The strength and feel of killing the ball reminded me of 900T, which surprised me quite. You know, 9.9K is a slap in the face! Table tennis is very good, and it can be played easily when physical strength drops. The smaller the resistance when swinging, the better the result. 9.9K catching and killing the ball, I like it, too. But I need to control my strength carefully to keep the ball out of bounds. The defensive performance of the racket is excellent.
Conclusion:
It's almost three years since the release of NS9000 series. During this period, Yonex has been very diligent in the research and development of every detail and specification of new technology. NS9900 is known as the fastest racquet speed in NS series, and this technology is also used to kill and hit the ball (what do you mean? Flat push? ) has brought more power. It is conceivable that Yonex NanoSpeed series NS9900 will be another breakthrough in technology, design and practicality. With the improvement of the durability of the racket frame, the service life of the racket is longer under the condition of high pound tension and frequent threading.
For advanced players, I suggest using the size of 2U, because generally speaking, 2U rackets are more durable under high-pound tension. But it doesn't mean that 3U is not good. Many people think 2U is too heavy. For those who are interested in upgrading from NS9000 S/X to NS9900, you can do it now and you will never regret it. Quoting the propaganda language of the racket "moving like a butterfly, stinging like a bee", the racket hits like a top-heavy attack racket but it is easy to master. I have to say again that Yonex and their R&D team always make the best badminton rackets. With the arrival of NS9900, your game will be different this time.
I will grade the racket according to the feel, control, strength and defense, but these are all based on my own tests and opinions, which may be different because of the user, tension and ball line.
General feeling: 9.5/ 10
Control: 9.5/ 104
Strength: 9/ 10
Defense: 9/ 10
Flexibility: 9/ 10
Advantages: design, technology, racket speed, durability, good control and flexibility.
Insufficient: price
Applicator: Intermediate/Advanced. The so-called MP of singles/doubles players is an arched groove protruding like a crescent between the line holes of the racket. This design seems mediocre, but it actually has the following advantages.
1. Eliminates the stress at the contact point between the wire hole and the wire: generally, the wear of the ball wire comes from the contact point between the wire and the wire hole to a great extent, that is, the point where the wire hole is inserted left and right when pulling the wire, as shown on the right side of the figure. The arch shape of MP can make the contact point flat, reduce wear, prolong the life of the ball line and keep the tension (tightness) of the line longer.
2. When hitting the ball, because the line is in contact with each arch, there is no problem that the hitting force is absorbed by the connection point, so that the hitting feeling goes out with the racket and the hand feel is more accurate. And because it reduces the loss of hitting power, it makes the ball faster, which is why it is called MP.
But ... this reduces the life of the racket, because the groove and the depression of the groove connection point are the weakest parts of the racket, but they are more likely to be damaged than the previous rackets. LATer, because YONEX developed at technology-titanium armor technology, MP's strength advantage was lost. Later, in order to follow up the speed storm brought by badminton 2 1 scoring system, NS- nano series directly replaced MP, so MP gradually faded out of the mainstream stage of history ... but many professional and amateur players deeply miss its balance performance.
Among MP series, the most classic is MP99, which is characterized by balanced performance and no obvious weakness. Suitable for most people, it is recognized as a universal shot. Have fun!
