Just like there are different swings there are different master moves...
It's interesting so many golfers that use a lower body start down have back troubles....I was just reading that Greg Norman might give up the game because of his...the article is in the new Golf Magazine or Golf Digest.

I know where you are headed with this, Dave. -- your thesis on the Right Forearm Start Down -- but the truth is that every good player uses the Downstroke Release Sequence of 6-M-1. And the fact that the sequence is best monitored and controlled by The Hands -- Hands-Controlled Pivot -- is the essence of The Golfing Machine.
Norman's back problems are not the result of his Downstroke Pivot Sequence: They are the result of his Downstroke Pivot Motion. I should know: the same Motion basically crippled my own Golf Stroke by age 40. The good news is that I learned to Pivot properly, and I now play pain-free.
