Today I played a practice set that was called off by rain (we were about to start the tiebreak.) My forehand was very high though. I tried hitting with a lot of spin, but it just wouldn't stay 2-4 ft. the way I like it. It was a good 6+ ft. over the net and landed long often. I resorted to S&V to win most of my points, but I need to be able to hit forehands. Is there any reason why this might be happening?
