Daryl - wrote-: "If, at the start of Release, the Left Wrist , Forearm and Clubshaft are in-line (Primary Lever), the Left Wrist Flat and the Right Wrist Bent,
then you can only Angle Hinge (10-3-C, 10-3-D and most people who use 10-3-A). You need to Un-Cock and Roll simultaneously or you will bend the Plane Line.
You have no Choice. Get a bench and see for yourself or better, address an imaginary ball facing a wall with your Clubhead touching the wall. Position yourself at Release with a Flat Left Wrist, then Uncock, then Roll. You’ll see exactly what I’m talking about.
Start your downswing and stop at Release. Is the Clubshaft parallel to the ground and parallel to the Plane Line. If your Left Wrist is Flat (not bent) then your Right Wrist is Bent (Strong Single Action Grip) and if your Clubshaft is On Plane, and your Hands are approximately in front of your right leg,
then you are Angle Hinging. For a Hitter, that’s good because the Primary Lever is rolling (Pivot) while the Left Wrist is Uncocking. Look at your Clubhead at this point. It is slightly Toe Down. If you’re a Swinger, and everything looks the same as above, then you must use Angled Hinging too.
The swinger who uses Angled Hinging must not try a Sequenced Release because you will bend the Plane Line. Swingers can compensate the Simultaneous Release by using a Very Strong Left Hand Grip (10-2-D) and still benefit from CF, with the Left Thumb and #3 Pressure Point directly behind the Shaft at impact (Like many Pro’s). If you don’t, then you’re Switting. Keep in mind that the Right Wrist remains Level throughout for both Hitting and Swinging, or Simultaneous or Sequenced release.
Flat Left Wrist/Bent Right Wrist at Release is not compatible with Sequenced Releases. Bent Left Wrist at Release is not compatible with Simultaneous Releases."
--------------------
I have higlighted certain of Daryl's statements in bold.
I don't understand all these claims - i) that there is necessary causal connection between a swinger's grip and/or left hand position at the delivery position and an ability to perform horizontal versus angled hinging post-impact; ii) that a swinger who uses angled hinging post-impact must not use a sequenced release and iii) that a swinger's left hand appearance in the downswing means that he is using angle hinging during the downswing (whatever that means).
Here is a photo of Tiger Woods and Adam Scott at address and at release (delivery position).
Tiger has a neutral left hand grip while Adam has a strong left hand grip.
At delivery, they both have the left hand flat but with slight variations in the degree of toeup position, due to grip variations.
Both of them can employ horizontal hinging naturally in the followthrough.
I know of necessary causal connection between i) a golfer's left hand grip and ii) the degree of left wrist flatness at the delivery position and I know of necessary causal connection between either i) or ii) and a golfer's ability to iii) perform a sequential release swivel action and square the clubface by impact and/or iv) a golfer's ability to perform horizontal hinging in the followthrough.
