I use a PST, im a 5.5 player, and I just don't understand why any high level player would use a pure drive, let alone roddick, benneteau, marc lopez, etc. Its a trampoline; under pressure theres no stability and the ball goes absolutely flying. It's like a toy compared to other racquets. I'd like to think that people that are at a high enough level can generate their own power, and that control is something needed in a racquet. Not to say the PST is the way to go, im just saying that literally every racquet 100sq or lower (so midplus and lower) don't even come close to this frame in terms of how ridiculously powerful, lack of control and toy like it is.
