I took the footage of Waite and Howell at the 1999 Michelob Championship at Kingsmill...My former partner in crime "Scooter" took the footage of O'Meara, Faldo, and Hoch at The 1999 USOPEN at Pinehurst No.2 when I was working with Clearwater...
The whole purpose of this layout is to demonstrate the different plane angle variations with the corresponding hand paths and the relationship of the left arm to the baseline...
I would strongly recommend studying the different amounts of shoulder trun, hip turn, leg action, etc...it will reveal may different relationships for strokes made from different backstroke plane angles...perhaps study the "MorePics"....
I have plenty of more "stuff" to share...

Powerful....
Do what the words and the pictures mean...
Now we're talking another level....
Your learning will get exciting....

PS. I have video footage of Bobby using Snap, Random and Full Sweep at different points of his career...
