Wrist action grip choices

Thanks for commenting.

Very interesting post.

I used to have a 10-2-B grip that was more like 10-2-A, but I have recently adopted your suggestion of ensuring that the left thumb is on the aft side of the club.

I do agree that a 10-2-B grip allows the left hand to roll-over naturally into a horizontal hinging action post-impact. I presume that this natural roll-over action is more difficult with a 10-2-D grip, which would predispose to angled/vertical hinging and a fade.

I never though about the other potential advantage of a 10-2-B grip - that the natural roll over action allows for a better use of PA#3 transfer power. That's a good point.

Considering all these advantages to a 10-2-B grip, wouldn't it be the "best" grip choice for most golfers? Are there any major disadvantages?

What about hitters - is there a "best" grip choice for hitters?

The use of accumulator #3 is really based on the clubs design, with a 10-2-A grip, pitch elbow, CF, and a true snap release, there is a lot more power (speed at least, and mass if lag pressure is maintained) - ala Hogan.

That said, 10-2-A, in all but ideal alignments and rhythm, requires you to 'do' something to square up, which most folks don't (hence why they slice given the 'training' grip).

10-2-B still requires that hinge action, the closing door, to ensure a square face, less power than A, but more than D. the happy medium. Its limitation is that most people steer, so the door still never closes.

10-2-D takes care of squaring up, but at a power loss, and potential direction loss for swingers. The best choice for learning to hit, because you can simply thrust the right arm paddle wheel at the aiming point with a bent right wrist. Since hitters don't use #3.

So with A - better to swing
with B - you can do either
and with D - hitting is a safer bet for control

Ed,

Excellent post!

Thank you for a great learning experience.

World class summary, Edz! Does anybody have any idea how Duval and Couples, Daly (I meekly submit they use more of a 10-2-D) overcome the power reduction that 10-2-D represents for most, due to no transfer power. I use a 10-2-B, but all the long hitters I know have a turned left hand!
Again, fantastic summary!

I am curious to see how your question gets answered.

I would add another related question. If a swinger powers the golf swing with a 4:2:3 release pattern, what % of the total power is due to PA#3 release? In other words, does PA#3 produce power independently or does is it simply transfer power?

Another related question is how can PA#3 produce power independently if the release of PA#3 is essentially passive - due to external rotation of the left humerus that happens naturally/passively during the release of PA#4 and a small amount of left forearm supination, which is merely a passive reversal of the left forearm pronation that occurred during the start-up swivel action?

Remember, Grip Types, per 7-2, are taken at Impact Fix per 2-J-1. In the case of the player that does not use Fix 7-8 or adopt it into their Address Routine 3-F-5 than Impact itself can give the best indication for the Grip Type taken. In the case of Couples and many other longer hitters, who starts their motions from Adjusted Address 8-3, their grips are dramatically different from their grips during his Impact 8-10 alignments. Mr. Kelley sated per 7-8, In-put-Out-put Power Ratio also is utterly dependent on Hand Location at Impact.

I understand that to mean that the there must be forward shaft lean at impact with a flat left wrist and bent right wrist. I don't think that it refers to wrist positional variations at impact.

My response was to clarification in determining Grip Type for Long Hitter (10-2-B vs. 10-2-D). "In-put-Out-put Power Ratio also is utterly dependent on Hand Location at Impact" was to stress the importance of how the longer Hitters achieve their length and the alignments of Grip Type. I did not mention wrist positional variations at Impact directly, but all of the reference numbers I mentioned can be tied directly with 4-0.

In Couples case, he is one of the few modern day players who really harness CF, and the physics of swinging.

He still has transfer power, and IMO he does this because he 'cups' his left wrist at the top. That allows him to still utilize the physics of a swinger's sequenced release (transfer power), while not having to 'hold on' to avoid hooking (also compensating by his open alignments). Note that his back is taking the force of some of these compensations though.

I would consider Duval more of hitter's move, who doesn't use the swinger's sequenced release and PA #3 much. What he does have is the hitter's 'mass' at impact from his right side. As much as a swinger may be limited by 10-2-D, a hitter can take advantage, allowing a full right side drive of the right arm without fears of hooks.
