Well i don't know now. I hit tonight and just used a freshly strung racquet and everything feel good again. I think that i was in a rhythm tonight as well, but I still would like to invest on something to counterbalance the head when my string is not fresh.
kosmikgroove, I saw what you are talking about on a site, but I don't want to mess up my 200 dollar racquets w/o knowing what to do. THANKS GUYS!!
