We bought this for my son and he loves it. He said it helps put top spin on the ball and gives more power to his shots.
I'm 16 and I bought this racquet for my high school season and It only took a good week to really get comfortable with it. You really get to appreciate the extra length when it comes to serving, the added height with my 5'2" frame really helped and allowed for ease with overheads. Sometimes with my given height the racquet tends to scratch the court a little with the top but no real damage and holds up nice and firm. Babolat did great with this one.
I bought this Racket for my son and he just can't think in other racket that he play before. I tested on my serve and I found that made my shot go on the box with not too much of the effort. I practice with him and this racket show a tremendous spin.
