I find when I'm limiting myself and holding myself back, I play much better. When I swing between 60-70% on my forehand, IE, I'm able to produce controlled winners, great placement. But when I play someone better, and they get these back, I swing much harder and the ball flys on me. Hitting the fence. My question is, what is your percentage of strength roughly for A: a rally ball. And B: going for a winner. And what are some things to do to hit a proper winner when in position to put the ball away?
