So I was playing with my friend today, and I noticed that my 2 hand-backhand was fairly flat. I tried switching grip, but that just made me hit the net more often. I tried putting more speed in my swing, but that just made the ball sail out of the court with little topspin added. Then, I tried to have a higher follow through, but that also made the ball hit the net more often - when it made it in, it had little pace on the ball. I read some threads about this matter, and most said that it is fairly hard to hit a lot of topspin with a 2 hand backhand. Any suggestions? Comments? Concerns?
