just to update this thread..... I am making some real progress finally with my serve. I am learning how to really let the arm and wrist go and be looser throughout the serve. I played a league singles match last night and served the best I have in a while. I am finally starting to get a repeatable rythym and everything is falling into place more and more. I still struggle to get the racquet down my back, but I feel like it's getting better all the time. I will post another video soo to show you guys my progress. I really appreciate all the help form everyone. It has started to payoff.
Currently using a Graphene Speed MP w/ multi/copoly hybrid @ 55/52
