So I've been trying to work on flattening out my forehand because I'm hitting too many loopy topspin shots even when I'm coming inside for a winner. Some guy I play with made the comment that I hit with too much topspin because I'm always stroking low-to-high (as in racquet head drops way lower than ball during takeback). Last night at my club I was watching some guy who is probably 5.5-6.0 practicing his forehands. He was pounding mostly flat shots, and it looks like his racquet does not really drop below the ball during the takeback, so its not as much of a low-to-high as my shots are. Is this one of the main differences between stroke pattern of flat vs. topspin?
