I have a friend who had shoulder surgery last summer. He has started playing again and has been looking at the POG because of it's high ratings in shoulder and elbow safety. His main concern is serving and what will happen when he starts playing for real. However, the 93 headsize is probably too small and he doesn't like the 107 because it's too big. My question is: Would the 100sq. inch NXG graphite be a worthy compromise. I have never hit with any of these racquets so any thoughts would be appreciated.
