My friend, these three rackets are very different ~ ~ Unix AT700: the middle pole is hard, with a warranty of 25 pounds, and the material is high-coefficient carbon fiber. Suitable for killing offensive players after singles and killing the ball in the backcourt. Both will do. Tennis needs a little strength, and it is easy to get off the net without dyeing. It belongs to high-grade auction, and the market price is 1450 yuan. Super Wave 799 and Super Nano 7 are both successful mid-range lenses, both made of high-rigidity carbon fiber. 3U is guaranteed to be 28 pounds, and 4U is guaranteed to be 26 pounds. Shengli Chaolang 799: Although the racket frame is not equipped with AT700' s racket head and thin-film titanium armor, the racket frame of Chaolang is made of nano-materials, with a rhombic cross-section and stable racket frame. The racket frame has a groove, which has good elasticity in handling small balls, and combines the moderate hardness of the middle pole and the quick recovery of the middle pole when killing the ball. It is a racket with both offensive and defensive capabilities, regardless of singles or doubles. Market price 760 yuan. Super Nano 7: The winning shot is moderate, which is a beat with rave reviews on the Internet, but it is an old classic beat. Like Superwave 799, it's nanotechnology, diamond cross section. But there is no groove technology. It is not as good as the racket with moderate hitting in Super Wave 798, and the market price is 700 yuan. Neither singles nor doubles, both offensive and defensive. Doubles are very resistant to collision. In addition to being a special expert of Soso, I am also a shopping guide of Xi 'an physical store.
