Too me—and it may be just me—but this thread is silly.
I have been traveling around doing lessons on the road now for about 6 years.
Somewhere in the middle of it, I started to get a little better player, like a 8 or 9 handicapper.
I'd ask them, "Tell me about your game."
A few DOZEN times they replied, "I was a 15-20-25 'capper, and I got your Never Slice Again video, fixed my slice, and now I am an 8 an need some guidance to get to the "next level."
I'd never seen these folks before in my life.
So, the idea that an idea needs a teacher to baby-sit it 100% of the time is complete and utter BULLturds.

All the stuff about the best way to teach a beginner could be argued for an eon, until there is a MASSIVE sponsored test/research.

My OPINION is this on beginners: I have taught them short-to-long, with and without a ball, and full swings first with a ball and without.
I think it depends on the ability of the teacher.
