Regardless of where the Clubshaft and the Clubhead are joined together, it always feels as if they are joined at the Sweetspot - the longitudinal center of gravity, the line of pull of Centrifugal Force. So there is a "Clubshaft" Plane and a "Sweetspot", or "Swing', Plane. But herein, unless otherwise noted,"Plane Angle" and "Plane Line" always refer to the Center of Gravity application. Study 2-N. except during impact, the Clubshaft can travel on, or to- and from, either Plane because Clubshaft rotation must be around the Sweetspot - not vice versa. So Clubhead "Feel" is Clubhead lag Pressure(6-C) and is a Golfing Imperative. (2-0). If Lag pressure is lost the Hands tend to start the hosel(intead of the sweetspot) toward Impact - that mysterious "Shank". When in doubt, "Turn" the Clubface so both the Clubshaft and the Sweetspot will be on the same Plane at Start Down. Both Planes always pass though the Lag Pressure Point. Study 6-C-2-A.

What is the effect on the analysis if Clubshaft/sweetspot and lag pressure point are on a plane that does not intersect the plane line? In 6,7 and 8 they appear to be on a plane that extends beyond the plane line.

I would agree that Frame #8 he's off the baseline...however...in the other frames he's picking up the plane line on the floor that is being traced from the target back to ....You have to remember one key piece to this puzzle...the model is a PGA Tour Veteran who is not sure what the string is doing on that club...much less knows what a plane line is.....So we all here at TGM Central are way ahead of the learning curve...than persay a PGA TOUR Player who is attempting to learn tracing...

<<all of a sudden you no longer see the LCG in the last frame>>

I was just asking if his position had an effect on this conclusion because 2-F has emphasis beyond what was originally referenced. Certainly, it was not my intent to be critical of a tour player. TGM Basic Plane Angles are importantly different from what Hogan and prominent instruction presents.

I appreciate the introduction of this subject.

Sweet Spot Thru
We have spent a great deal of time dealing with where the LGC is at the Top in relation to the Left Arm Flying Wedge. But where does the LCG line up at Impact and Follow through?

Annikan is on a roll
Annikan,

Your LCG and tether discussions have transformed my game and understanding of TGM--to quote Jim Krammer "Mega Mad Bullyas to you my friend"--thanks.

I have keyed in on how the thumb and thumb pads incorrectly tug against the LCG when one grips the club thinking only on the club-shaft plane. Only when one really gets a sense of the Longitudinal Center of Gravity can one hold the club in proper balance. Its amazing how quickly the thumbs can choke this balance off, and create some ugly results.
