Golf as a three lane highway, the pivot, the arms, the hands.
Looking back at some of the clips of Nicklaus in his prime and at Moe Norman, I got to thinking about what that 'three lane' highway could mean.
Consider for a moment, a 2-D view from above the golfer.
Moe Norman is known for saying "my club never goes out of bounds", and by that I think he means he had a 'narrow lane'.
Imagine that 2-D view from above, a dot representing the sweet spot at address, another the hands (PP#1).
By a 'narrow' lane, what I am saying is that the distance from the sweetspot at address, and the sweetspot at the top/end, is more narrow for an accurate player.
That doesn't require a steep plane per se, but certainly shows why a steeper plane can be considered more accurate.
Take a look at Kenny Perry's motion from this 2-d, above the golfer perspective. He keeps the club very much in front of him. The sweet spot never gets behing PP#1 when viewed from above (or does so much, much less than others).
Same is true for Furyk.
That distance between the sweet spot at address and top is a 'narrow lane'.
Nicklaus is perhaps one of the best examples.

Im thinking that if the clubhead actually does stay outside the hands ..........the clubshafts butt end will not point at the plane line on either side of the ball. Which would break a bunch of 1-L's wouldnt it? 1-L-18 and 1-L-5 certainly.
Ive been seeing some nationally ranked amateurs up here, taking full ish practice swings with a dowel stuck in the butt end of the club. In this way the clubhead does stay outside the hands in the manner you mention but only on the through swing. So they are Plane Line compliant in TGM terms going back but not going through, where the butt end points to the ground behind the golfer. Mark Evershead style maybe. No Release Swivel or turning of the back of the Left Hand back onto the Inclined Plane after the club switches ends post Follow Through but a fully maintained bend to the Right Hand. Sean Foley who is pals with Evershead might be one who teaches this, not 100% sure. Evershead studied under Tom Tomassello, did he talk about this stuff?
Its an interesting concept but its not a clubshaft plane literally, in that the entire motion of the Clubshaft does not lie on a flat plane throughout and planes are flat by definition. A bent plane is not a plane anymore right. Although Homer himself defined a non clubshaft plane, a clubhead only plane of motion for the Angle of Approach. I dunno, that is probably a totally unrelated concept. And a can of worms, visually equivalent worms though.
We've got some friends right here on this board who teach the dowel in the shaft drill. Not sure how literally they take it when really hitting? Good guys all and super players too. Maybe they can share their findings with us.
We're in the Lab after all. Go nuts. Ill have to tell you about my intentionally bent left wrist shot sometime. Best done with zero structure and throwaway. Got it from Ernie Els even. Its in his old short game book actually.
