Hi there, this is my first post/topic in BC, although I've visited here almost everyday for the past year or so. Basically, I want to know if the grips have a significant effect on your performance. Below is a short story of what I experienced yesterday and today. For the past few months, I've always had towel grips on my G3 AT700 LTD, 3U, string is BG80 at 25lbs. The grip size felt huge, so the head-heavy feel was almost gone, and I had no problems with arm or wrist pains (except the first day that I used it as it was completely new to me). Yesterday, I changed the grip into Yonex Super Grap 102EX. When I first held the racket, it did become head-heavy like it was supposed to. However, when I started playing, I missed almost every shots, i.e. backhands, clear, drops or even really simple shots, by hitting on the frame. After the session, I experienced wrist pain. Today, I played again. This time, my shots were A LOT more accurate. My arm (Infraspinatus part) is in quite a big pain which I never experienced from using the racket. So my final question is: do the grips change the performance significantly? Or it could be the fact that I didn't get used to it? Or was it because of the head-heavy mechanism from AT700LTD? Thanks for any help!
