Question: In your own experience, what side is the most effective use of this material; defense or attack?
Document: I love to play with these professional Tennis racket as they made from well designed rubber material and loves to use them
Its nice, its thicker enough to protect the paddle, but why this size and this shape.... it gives you the idea that they have a residual of material and they want to use it in something to do not waste it... I was deciding to use this or keep my current pouch (follows the shape of the paddle... more sexi... lol).These are my first impressions. I expect to have more after I start using the paddle...
With this racket, I feel great; I rely on serve, spin and defense and this racket has been fantastic so far.There is one issue though that I didn't have with X4002, that the handle feels slippery and I fear sometimes that the racket may slip and fly away. It hasn't happened yet, but I feel it a bit slippery and I end up constantly wiping my hands.
While I didn't buy the racket from Amazon, I still bought it from the same vendor listed here. I had a X4002 racket which was good and with the $50 won in the office tournament I was itching to get a better racket and finally decided to buy X6002. This racket is a huge step up from the X4002, is lighter and is fantastic for defense; the expression that you see on your opponents face after you've returned a fierce smash is priceless!
Awesome racket. It has a sticky rubber for good spin, but at the same time it can generate great power and speed. It's not too bad for defense either, but its offense is better. If you are a beginner/intermediate player looking for a racket to boost your game then this is the one. If you are a all-around or all-around offensive player, this racket will especially complement your game. It's great for forehand topspin and some backhand shots. It's a great quality racket overall
This racket is pretty damn good! I just need to play better.First off, this racket can hold up against any crazy spins, speed shots, and allows you to play a decent defense. The rubber on it is fantastic and it has some pretty good weight for my taste. I can generate really good spins and power out of it. The one thing that gets me is the sound of it. I typically play gentle chops and placement shots.
Like it. I am not a professional player but it is good for me to use.And it is not so expensive
Great paddle love playing with it. Was easy to get use to. Made my game 100% better night just love this paddle.
Double  happy with bat :). It's improved my game. Very good for looping and smashes. A little on the heavier side but that's how I like my bats to be.
Far better than my previous racket, which was entry level and cost about the same. This racket is easy to handle, great control and lots of spin. A bit on the heavy side, but not an impediment.
Answer: yes
