I've had a wilson prostaff 7.6 for about a year now. It was a little different to hit with at first but i have been very happy with it other than how badly the strings get crooked when hitting with lots of spin. I was told that the main purpose of the rollers on these racquets was to increase the power of the ball when hitting with topspin and was just wondering if this was true? people always ask me what they do and i'm not entirely sure. i now play primarily with the wilson triad 6.0 that i bought about a week ago, i just couldn't pass on a $200 racquet on sale for $100 especially since i have played with it before and loved it. thanx guys!
