Well, this ain't saying much becaue other than Fed and Nadal>>> none of these other pros you are speaking about using these larger frames are doing much on tour. Perhaps they should go to a larger frame??? :roll: Like you said, pros are going to use the headsize that produces the best result. Fed is using a 90 and I would say with 11 slams under his belt (which blows away all current pros and many past pros), it is pretty good. Not too many pros are using 105-110 square inch frames either. And I can't remeber the last one to win a slam with one. I think the 90 is doing much better.
