Finally, something on this site I know the answer to. His method is called the 'right sided swing' because that is the only 'half' of the body that moves in his method. He likes people to get into their impact (impact fix for you TGM's)position, (ie. weight on the left leg, hands at impact, etc.) and keep your body in that position during the whole swing. He calls it maintaining you body angles thru the swing. More on his method can be found at www.garyedwingolf.com.au. Don't think there is really much comparision with TGM hitting/swinging.
I think he has some good stuff BTW...I have found putting more weight on left side to be really useful for a lot of shots. (not all tho)
It would not be Impact Fix tho....Impact Fix is hands forward, shoulders and hips open...the whole deal. It is a rehearsal of what you would be like at Impact. As close to it as you possibly can.
