Couples
 

Good responses!!

So... is someone like Fred Couples, who has a bent left at the Top, using using Double Wrist Action, or Single with a bend(because of his grip)?

Per 10-2-0 . . .

10-2-0 GENERAL Grip Types are classified according to:
1. Whether the Hands are at right angles or parallel with A. each other or B. the Ground
2. The location of the #3 Pressure Point
3. The extent of certain Wrist Action per 10-18-0. Two Actions – Horizontal (4-A) and Perpendicular (4-B) regardless of Rotational Positions (4-C) – plus two Wrists make possible four combinations of Actions.

10-2-D is Couples grip and this grip is called Strong Double Action because the Left Wrist not only cocks but bends.

This should also shed some light on it . . .

10-2-G TRIPLE OF QUADRUPLE When the above Grip Types are MODIFIED by Rotating the Hands so that either or both Wirsts cannot Cock On Plane without also Bending, Feel loses its geometric basis. Also the natural Wrist motions conflict. A bit of Left Wrist Turn properly becomes exactly the same amount of Double Wristcock to keep the Clubshaft On Plane and to maintain Impact Wrist Position. Except with a “True” Swing (6-B-3-0) where Centrifugal Force will produce the “geometric” Flat Left Wrist when there is actually a “visual” Bent Left Wrist. That is, the Clubshaft and the Left Arm are in a straight line per 6-B-3-0 and 2-K regardless of the Left Wrist Position. These procedures may be either “Weak” or “Strong” but either or both Wrist are Double Cocked per 10-18-B.

Yup, the usual grip that 'traditional' teaching has the thumb and 1st finger pinched. The 'weak' single action and weak in the sence that the left thumb and pp3 is turned to the top of the clubshaft. To do this grip is problematic to do due to the fact to get the no.3 pressure point on top it is hard for the right wrist to not be turned from vertical. It is 'essentially' possible though. The left wrist will remain unaffected(and is a likely result of the no-gap between the thumb and forefinger style when the wrist is flat to vertical) to repositioning the left thumb and in the photos 10-2-A/B, it is exactly the same as the strong single action grip in 10-2-B apart from the fact the thumb is now on top of the clubshaft instead of aft. Anyways what I'm trying to say is that the strong and weak single action differ only in the location of the pressure points - ideally they will not be 'turned more' from vertical.

Look at any impact pictures of freddy - you will see that his wrist is not flat against the vertical plane of the hinge action, it is pretty turned. What becomes 'his' perpendicular motion of #2 ... think about it....

Good

Very good all! Keep it up!

How about... Zinger, Duval, Langer, Ed Fiori, and maybe some will remember Judy Rankin?

Classify Grip and Hinge Action...

10-2-D STRONG DOUBLE ACTION T/V/A Now the Right Wrist is Vertical and the Left Wrist is Turned to the top of the Clubshaft so that the Left Wristcocking motion will be on the same line as the Right Wrist Bend. The #3 Pressure Point and the left thumb are also on the same line as the Right Wrist Bend. Double Action – same as 10-2-C.

Very compatible with the Cut Shot procedures. Any Left Wrist Bend at Impact Fix should be maintained throughout the Stroke.

This Grip Type features maximum Wristcocking action and strong support for both Acceleration and Impact loads. The palm of the Right Hand moves toward Impact exactly like a paddle-wheel rotating On-Plane – no separate Rolling Motion until after Impact. See 10-10-C.

10-10-C ANGLED HINGE ACTION This simultaneous “Closing and Layback” procedure holds the Flat Left Wrist vertical to the Inclined Plane (2-D, 2-G). This is identical to the Paddle-Wheel motion of the straightening Right Arm but is a superior procedure (1-F). It greatly simplifies Hitting (10-19-A). The Shoulder Turn changes the appearance of this 10-18-C Wrist Action but not its Feel (see 7-10). Its Slice tendency must be compensated per 2-J-1. The “Laying Back” action makes Ball location very critical. Study 4-D-0.

1-F RIGHT ARM OR LEFT . . . However, you will save yourself much anguish by using the Right Hand just for sensing and controlling acceleration and the Left Hand just for sensing and controlling alignments. Right Hand – Clubhead. Left Hand – Clubface. Essentially, the Left Hand should be consciously Monitored (5-0) from Start Up (8-4) to Finish (8-12) so there will be no unintentional or panicky wobble. See 6-M-0. And variations in Elbow Bend and/or location during Release will disturb Clubface control by the Right Arm, making it an inferior procedure (7-2).


Zinger





You didn't ask but Buck

I think the answer to the question "How flat is flat?" can be found in the right wrist bend at impact fix. In this location the right arm flying wedge includes a precise amount of right wrist bend. Your left wrist will appear flat and vertical or your hand will have some degree of turn on the grip. As long as the right arm flying wedge with its fixed degree of right wrist bend is maintained, then you'll have a geometrically flat left wrist.

Backstroke visual check (swinger) is straight foreword. The flying wedges are assembled (swinger) at the end of the takeaway, aproximately two feet back. The right arm flying wedge is completed and includes its precise amount of right wrist bend. At this position the amount of visual left wrist bend is only the result of a turned left hand at impact fix. This visual amount of bend should exist at the end of the backstroke. Attempting to flatten the left wrist to comply with visual flatness will affect the wedges.

Other End
 

Daryl's answer and Bucket's pictures are good!

The other extreme would be guys like Johnny Miller, Olazabal, and Pavin. Hogan is sometimes said to have a "weak grip"(non-TGM term), but I don't think it is quite like these guys.

Great post!
