Welcome to LBG RONOC.

Thats a big question and an interesting one too given the variety of options and differences of opinion. Even amongst TGM instructors it would appear. The 6th recommended 10-13-A while in the 7th it was changed, perhaps by later day editors to Rotated 10-13-C, I believe, I dont have the 7th. Despite the fact that Homer suggested that Rotated was normally confined to Shiftless, shorter shots.

To my mind the advantage of Standard Shoulder Turn, 10-13-A, Flat back and On plane going down is that it allows for the shoulders , the right shoulder specifically to take the Hands and club directly down a flatter Turned Shoulder Plane. A flatter plane angle which would more closely approach a shaft plane and therefor require less of plane shift to get back to the shaft plane (or lie angle which we must for clean contact without any toe up or down).

Homer realized we might not be able to get the right shoulder all the way over to the shaft plane and in this regard he recommended we select a higher plane if necessary. See 10-13-D.

So this sort of a shoulder turn, which seems weird at first in that the shoulders travel a different path back and down, has some geometric advantages to my mind. Assuming you sequence your Downswing properly (6-M-1) ground up, the Right Shoulder will be taking the Hands down a more desirable Hand Path. The selection of a higher Inclined Plane that isnt a TSP can see the Right Shoulder take the Hands and club out over the top, above the plane. A predicament some solve by dropping the Hands vertically prior to turning the shoulders.

This Turned Shoulder Plane and proper downswing sequencing together with Axis Tilt, a sliding of the Hips to Tilt the Spine and lower the Right Shoulder is practiced with the " Downstroke Waggle". A really great drill. I do two after a pull shot on the range and the pulls disappear immediately. The cure for "Roundhousing".

Thats what Im thinking anyways. All the best for '10, RONOC. You can hit the search button for those terms if you need to.

Man O.B. Maybe I should just travel to Toronto and take a lesson from you. Very good stuff!

RONOC, sorry I didn't notice you were new here. Welcome! Please copy and paste O.B.'s great post. You might not realize it yet, but there is a WORLD of TGM answers in there that you will need for years to come!
