I think he is already uncocking the left wrist WAY too soon! He needs a max
trigger delay, snap release, in order to "crack the whip".
You're right, Mizuno Joe,
Jim is "Uncocking the Left Wrist way too soon." In fact, I'd be
very surprised if he wasn't Uncocking right from the Top (the Hand Throw of
10-20-A). What he is not doing is Loading. The Drag from
the Top will give him that. Then, by the time he's felt that Pull, he will
have Delivered the Load far enough Down Plane to begin a Non-Automatic
Random Sweep Release per 4-D-0.
There is no question that longer-term, Jim will achieve his Maximum Power by
using a Snap Release with Maximum Trigger Delay. But that is way too much to
expect from a Powerless Person. If he follows my advice,
he will have a good chance at producing a Line Path Delivery (10-23)
instead of a Circle Path (10-23-E); a Wrist Throw (10-20-E)
instead of a Hand Throw (10-20-A); and a Non-Automatic Random Sweep
Release (10-24-B) instead of a Full Sweep Release (10-24-A).
If he can make these improvements, then he will have made major progress.
Then, he can continue his journey toward Golfing Perfection. The steps along
the way would include:
1. Pushing the Non-Auto Random Sweep into an Auto Random Sweep (10-24-C);
2. Then, to Non-Auto Snap (10-24-D);
3. And finally to an Auto-Snap (10-24-E).
4. Along the way, he should make his Wrist Throw automatic by
Triggering it with the Delivery Path Throw (10-20-D).
I write these words knowing that the above 'itinerary' for Jim's journey is
sound. But the reality is that he needs much more than a Travel Agent.
Can someone explain the wrist action of Swingers and Hitters? What is Wrist
Turn and what is Single wrist action? What is wrist cock, what is wrist bend?
Get The Book, 300Drive.
Study Chapter 4, specifically 4-C-2. Then hone in on 4-D-0. Then study 7-18
and 10-18, specifically 10-18-C. Then study Chapter 6, specifically 6-B-2-0.
