Interlock or overlap?
Which girp is better for the Golfing Machine principles? Seems like I get a improved finish swivel when I use the overlap because my full left hand is on the grip. Is this my imagination working?

I have never seen in the book a preference between interlocking and overlap. I have gone back and forth and while I have smaller hands that usually dictate interlock, find overlapping more comfortable. If the hands are educated it should not make a difference what connects them. I pay a lot more attention to my left thumb than my right pinky.

I think two other issues are more important than type of grip.

1) grip pressure.
2) how relative "strong" or "weak" the right hand is to the left

then I think you will figure out what type you might like


Consider the function of your hands when you hold the club. Do you want single action or double action?

Do prefer vertical alignment of the wrist or more predetermined roll of the wrist at address ie stronger?

Not in the book, but I personally think that the interlock tends to move to an angled hinge, and the overlap to a horizontal hinge.

Certainly worth experimenting based on your pattern/components and desired hinge.

I'm sure someone with more anatomy knowledge can give more detail, but when I interlock the left forearm rotation is checked, it just doesn't want to roll.

I'm guessing it is in part due to activation of the muscles supporting the thumb and forefinger of the left hand (separate your index/middle finger in a 'V' as wide as you can to feel what I'm talking about.

Sorry I can't give you more, but at least for me the difference is clear.

Just saw some video of Ryo Ishikawa's swing. He actually appears not to have the left forefinger on the grip at all. I think there is something about all five fingers on the left hand being on the club encouraging horizontal hinging.

I see what you mean. My left FOREARM doesn't want to roll independently as easily with interlocking as opposed to the varnum grip.
This brings up the discussion of how one wants to "turn the club over" . I agree that interlocking grip seems to promote angular hinging motion.

I agree. Especially when Chipping and Pitching.

With an Interlocking Grip, with any tension or lack of Right Arm bend, the Left Wrist doesn't seem to want to fully Uncock which certainly affects the Impact Swivel. Not that you want to be fully Uncocked at Impact, but by disturbing the Uncocking Freedom even the slightest seems to affect the 3 dimensional Impact.

There are days that any of that doesn't seem to be the case, but for general purposes, the Overlap ALLOWS the Left Wrist more freedom of motion.

The Little Finger of the Right Hand seems to grasp tightly when Interlocked. I think it's best not to allow that to occur.

Hello,

new to TGM and LBG... still diging out the wealth of information here !

A teaching pro told me that if you put pressure on the thumb and forfinger, this activate the muscles in the top of the forearm which restrict the pronation / supination. On the contrary, pressure on the last three finger activates muscles in the bottom of the forearm that do not interfere with pronation / supination.
