Hi, I'm, a 4.5-5.0 level tennis player and looking to buy two or three of these racquets. Reading this review it sounds well suited to me. I generate my own pace and have no trouble hitting heavy, penetrating balls. However, I have never done any real weight training or muscle toning exercises (especially for the biceps and triceps) so I'm not sure how I'd cope with such a heavy racquet over a long period of time. The racquet I'm using at the moment is Marat Safin's Head Prestige Classic 600, a 90 square inch frame weighing about 350g. This racquet feels so comfortable in my hands that it's like an extension of my arms but when playing 4-6 hours in a day (once a week) my right arm (right hand player) gets very sore. Is this a sign that my racquet is too heavy, or that I might get tennis elbow by using it so much? (I play about 18 hours a week). Also, my volleys are relatively average and I have trouble sometimes when hitting the sweet spot when trying to pull off a good kick serve. All advice is very much appreciated,. Thanks,
Tim
