Ok I just picked up a new Head Liquidmetal 4 racquet and after playing for a couple of hours a couple of days ago, my arm was killing me. Yesterday the pain was very bad, mostly just above the elbow. My question is, do those racquets have a history of giving people with long, fast swings arm problems? I'm a baseliner all the way, and I swing very hard, not because I'm always trying to hit winners but that's just the way I'm most comfortable playing. I figured that I'd be ok because I spent about a week with the Flexpoint 4, playing everyday with it and never had any problems and they are almost identical racquets except for the flexpoint technology. So basically my question is just whether or not the Liquidmetal 4 racquets have a history of giving arm problems and whether or not I should look into a different racquet. Thanks for any help.
