Did this happen to any of you ? I have been playing with 4 and 5/8 grip size for many years even though my hand sizing chart saids i should use 4 1/2 grip size. and for really odd reason, i kept on getting more and more comfy with bigger and bigger grip size and now i am using 4 and 7/8 grip size. I have built it up with Very thick replacement grip ( Gamma Pro RX ) and with 2 very thick over-grips like Pro supex overgrip. Now after 3-4 years, i am realizing that it maybe hurting me on the serve. I am finding that it is more difficult to pronate and control the serve with such big grip. Do you guys think this makes sense ?? and also i am getting late on some shots, does this make sense ?? What do you guys recommend ? should i go back to 5/8 as before ?
