Well, I want to subscribe to one of these instructional sites and I want to get some feedback from you guys. I used to get Tennisplayer.net when USPTA pros could get it for free and I was very happy with it. The feature when they analyze a stroke from a member and compare it side by side with a pro is very cool. Tennis One has that free SportsCAD Video Analysis Software, which seems like a nice tool. Has anybody tried it? I am anxiously waiting for you opinion.
