Lol, I think shootin4par is referring to me, so I will try to answer.
First of all, I was just introduced to the little yellow book yesterday, but I will do my best to explain in some of those terms if I can.
As far as I can tell right now, I emphasize a swinger-type method (not hitter) with vertical rotation on normal full shots. I also, without a doubt, believe in a TOTALLY passive rotation of the left forearm for those shots. Like 6bee1dee's reply states, I find that most people find this unnerving, to say the least.
So I often challenge them to go ahead and try to totally give up trying to rotate the club to square and let the club contact the ball on the hosel, if that's what happens. And I have found so far that 90 percent hit a right-to-left shot with a closed clubface the first time they become passive with their forearm rotation.
