I'm not Tom Tomasello's nephew...however, I had the good fortune to study privately with Tommy back in October of 1993 (three day school mainly on swinging). Actually, I had a hard time believing what he was teaching me back then. I was stuck in thinking the lower body started the downswing. Starting in 2003, I made a dedicated effort to follow Tom's instruction exclusively. Today, I'm glad I did, the results are starting to really pay off.
Tom Waston's Lessons of a Lifetime DVDs just released are quite something. Not a bunch of how I play golf, rather a collection of how many ways there are to skin a cat. I was lucky enough to chat to him about it a few weeks back. Grip and Transition rank right up there in hanging anything together in a meaningful way.
Great stuff. Impact hands throughout swing. Maintain cup in left wrist i e geometric flat wrist. Solid stuff nothing goofy. Good discussion of grip and interesting how he sets up right forefinge ie pp 3.
