Nicklaus, Tom Watson, and Miller lifted their heels and managed not to sway.Lifting the heel encourages a sway which makes your contact more inconsistent.
Therefore pros will never teach it.
I get your point that it could encourage a sway, but it can be done without swaying. I only opened the thread, as I thought it was interesting if you suffered from a bad back.
As I said I only saw end of the Rose piece, so not sure if he just used it in practice, just with his driver, or what.Perhaps someone else saw it at the Open Zone ?
