i use purestorm, and i often have arm pains and have to ice down... in fact, im icing it down right now after a match. i dont think ill ever be at 100% this season but some ice and rest should bring it to 80-85% most of the time.
andways, i dont htink its the racquet, its got a good weight, add a lil more might help but its a pretty solid racquet. i might be hitting frame a lil too much but i get pain from other racquets too so it might just be the racquet. but its not the most solid or flexible racquet either so isnt suppose to be good for your arm, but not many racquets are if u want some power, gotta give up something.
