Graham,
Thanks for posting that. I just had a lesson with a pro who suggested exactly this. I am doing this, and I really like the visual reference, eg. as my hands are overy my right knee for longer
clubs, I can start my release. (A little further in for shorter
clubs.) My experience is that this is the easiest way to create power in my swing with a lot less effort.
The only problem I have is with reconciling this with Greg's right hand drill, because whether you are rolling your wrists through impact by releasing lag, or "swatting", both are timing, right? Or is the take home message of the cupped right hand more of a "up and down, never side to side", but you will still need to time certain aspects of squaring the clubhead before impact?
Another question: How do you know/feel when you are loading your shaft? When does the flex in the club shaft start doing it's work?
