As for that King dude.....
(here:
www.golfpro-online.com/tuition/lking/index.html)
That's a pretty cool site anyway....lots of pics and swing stuff....(if you click on the lessons at the bottom of the page)
I skimmed through it....and a lot of seems to be pretty good.....the setup stuff seemed to be good (from what I got out of it from very quickly skimming)....
But then I got to lesson 6...
"The clubface MUST not roll open in the backswing."
...
Seems to be method teaching...
I mean....this would work for Palmer, Trevino, Lema, Irwin, Funk, Duval, etc...(anyone with that kind of clubface control)
But not for Hogan, Mickelson, Jones, blah blah blah etc. etc.
Personally, that guy wouldn't be a good fit for me...(I use Standard Wrist Action....i.e. with a swivel in the takeaway and right before the Release)...
