For future37....and others.
When Faxon was talking about a "TGM" position, he was talking about folks who are TGMers who teach on "on-plane" right forearm, and elbow plane address shaft positioning (or even a much higher Turned Shoulder Plane).
The book "literalists" love this position, and several others like Ben Doyle, like it too.
I used to teach it to most of my students.
I don't anymore.
In my opinion, it is NOT a natural location for the shaft, or the right forearm.
The right shoulder is MUCH closer to the hands at impact, and then, the location is fine.
I do use it—like in NSA2—for effect.
Brad Faxon would NOT be someone I'd use it on.
