That makes sense MJ .....thanks. Effective though Rolling is, its not a little bat or flipper, lever deal per say. Its more about optimal contact. Keeping the point of contact between ball and face intact "as if welded together", no slips or wobbles except for that due to club face loft.

Would you agree? If so what does that do to Hogan's "little bat" or A.J.s "da bat" ? It'd still work but not for the reasons described I guess. Interesting.

Ah ha! Now I understand Yoda's reference to "da bat"! :laughing9

A. Hinge action, a closing only club face (dual horizontal) will provide maximum compression whereas as vertical and angled will produce lay back therefore diverting the force losing compression comparatively

B. In order to sustain the line of compression the original contact point of face and ball must remain in contact through the entire impact interval ( which relates to hinge action) this is possible only if the motion or arc is uniform, Therefore there must be a perfectly centered action.

C. Any deceleration of the club unrelated to the slowing effect of two objects colliding. Such as bending the left wrist ( law of the flail) or any other mechanical inefficiency regardless of whether the sweetspot was hit or not will change the compression and separation speed

In other words... Hit that ball on the sweet spot with maximum separation speed by executing a horizontal hinge with a flat left wrist and a centered action

Secondly........



Please explain your reasoning. Do you mean to say that it implies that it rotates around the hosel because the handle of the baseball bat is at one end? Why does attaching a shaft to a little bat imply the face is rotating around the hosel? Does the little bat not also have a longitudinal center attached to a shaft? of course it does... If the little bat is attached to the shaft through the sweet spot then it would still be rotating around the sweetspot it's just that the hosel and sweetspot are in line

The term "bat" implies the sweetspot is given added velocity by face rotation, which doesn't happen because the sweetspot is the center of the face rotation.

The word bat does not imply that to me. if the point of the bat is to show you that a closing only club face produces more compression than one that does not... it is absolutely correct! It's not adding velocity to the sweetspot but rather the golf ball ( not sure velocity is the right word) I think there is nothing wrong with the little bat attached to the shaft. The horizontal hinge is JUST like a baseball bat because baseball is on a horizontal plane! Or at least ver close to it. The bat is a closing door without the distraction of the lofted face, just as the horizontal hinge is a closing door in golf we are not on a horizontal plane thus requiring the dual horizontal hinge

But here's a question .... wouldn't the increased club head travel associated with Horizontal Hinging (assuming some #3 angle of course) increase the club head speed for any given hand speed?

MizunoJoe,

I luv ya, man, but at Lynn Blake Golf, we never "choke". Down or up!

Hasta la vista Johnny Miller!

Instead, we only . . .

Grip down.

:laughing9

Serious Note to instructors: This is an important little point, guys, one that no doubt will spawn its detractors.

For me . . .

Grip down is the preferred alternative to . . .

Choke up.

Remember, the Computer is always listening.

And . . .

Complying.

:salut:
