I think you got it Tom! Though I am not a huge fan of trying new things in a match even a practice match. If you can cope with the impact a change (even a positive one) will have on your performance and the frustration it WILL cause at first, and all in the midst of a match you are a rare person indeed. Usually I just resort to the bad habits that I am comfy with and neglect the change. But tennis shows me all the time that we are all different. Good luck and I cant wait to see the vid.
