Do you think Mr. H. Haney is unknowingly teaching 10-6-D to everyone. Does O'Mera also employ this pattern?
Concerning Mr. Leadbetter... I did take some lessons from him, pre-TGM.
He is very good at making the one feel comfortable, and has a very good way about him when he is one on one. This was at Greenleaf...pre real big $.
The pictures in the back of his book (sequences) look very similar to the ones in TGM.
He seems to prefer a Sweep Load, and a Reverse Plane Shift. I never felt comfortable with the sweep load. He also wanted Double Wrist Action.
He "delags" players by replacing a beautiful snap release with a sweep release. This is pure incompetence. It's like cutting two of the spark plug wires of a V6 in order to slow down, rather than easing off the accelerator.
