Hi , I just wanted to say , after being coached from a lot of different coaches , and most of them saying different things. I have picked up lots of different techniques I can use , and I can switch between them. I just wanted to ask which was the "correct" one? Heres the technique I mostly use (obviously not exactly , but reasonably close) - http://www.youtube.com/watch?v=hnw89edmxX4&feature=channel I can use this technique If I want to - (see 5:30 - the racket is behind the mans back , and going downards) http://www.youtube.com/watch?v=EWqBVKNX1Js&NR=1 I can also use this technique - (pronation technique - I call it , so I got an easy search from youtube lol.) http://www.youtube.com/watch?v=p18RzaW94j0 So which one do you think is "correct"?
