Just so you are aware, I did not bring up Vic Braden. I haven't even acknolwedged him. The poster who brought him into this discusssion is, Suresh (although not even sure why he mentioned him). Here is his post:
The only teaching pro I have mentioned is Yandell. I'm sure you are familiar with his works. He has not only filmed hundreds of pros, but studied thousands of video shot at high-speed. Here are his thoughts.
I find it fascinating that suresh, ultra, bubba and everyone else that says there is a wrist snap on the serve, have yet to provide even one video of a player doing what they are saying. Even more fascinating is they keep quoting teaching pros, yet every one of those teaching pros does not provide any video evidence on their websites of a pro doing what they are advocating.
Lastly, I will mention, Braden. I too do not like him or his teaching style. However, he has been extremely influential in studying the bio-mechanics of tennis strokes, and has been a pioneer in this field. He also has proven thru research, high-speed video analysis, and help of others that there is no wrist snap in the serve, FH, or BH.
I will end with the greatest server of all time. No wrist snap:
