Well I first felt that the smaller grip size was the choice, 4 1/4 with over grip-- I might have somewhat smaller hands than an average 5 11 3/4 height-- however, as I have become stronger in the kinetic chain, it seems that i may need a slightly larger grip to really pound the ball. At first I felt that a smaller grip allowed for easier grip changes too! I have been feeling as though my wrist is the effected part with a small grip however. With a larger grip 4 3/8 with an overgrip I feel like I can plough through a little more stable-ized... Where-as I find the racquet has a tendency to twist more easily with a smaller grip. This is more noticilble with heavier topspin. I realize that the serve is supposed to benefit from a smaller grip size, but it seems that especially since a looser grip is more appropriate for serving, that a slightly larger grip makes it easier to grip more loosely. Anybody kow how tight my grip should be for topspin eastern/extreme-eastern forehand? Thanks...
