I only picked a few strokes which I think are my typical ones, and compiled them into a slow motion video. I think this works better than normal speed videos, but please let me know otherwise. http://vimeo.com/7404450 Any suggestions are highly appreciated. I have three specific questions: 1. It seems that my finishing up is kind of in between windshield wiper and over-the-shoulder. Sometimes I can get a lot of topspin without much effort, sometimes I try hard but get little. What am I doing wrong? 2. My open stance (the last few strokes) really seem awkward. My body (especially my left leg) lifts up but my right foot seems to be fixed to the ground. I also lean backwards. How should I correct that? Am I hitting the ball too late? 3. And finally, maybe I should just try to hit more with close stance? I feel like the weight transfer in the close stance help me hit more powerful balls. Thanks a lot!
