Not to get off track and this may seem needlessly precise or small but... There's something that isn't talked about
often which is Id say critical to a powerful , free flowing flail with correct on plane , Hand Motion. Namely: The re forming of the Bent Left , Flat Right Hand Condition post Finish Swivel.
Its not a Right Hand Release, capital R, a source of power but it does promote a full, free flowing and Aligned flail and in that way allows for full power. Its as if the flail needs some room or a place to go post impact, like a sprinter running another 30 yards past the tape.
Fix; Impact Hands (Flat left , Bent Right)
Adjusted Address: (B Left, F Right)
Top: Impact Hands
Impact: Same
Follow Through ; Same
Finish Swivel ; Same
often, ideally .
Post Release Swivel ; Not the same, (
Bent Left , Flat Right.)
Finish: Impact Hands
The condition of the left hand post Finish Swivel is Cocked, Turned to Plane and
Bent. Hogan did it, Moe did it, Bobby Jones did it........Lynn does it!
Sure you can do otherwise; Angled Hinge a three quarter shot for instance with a Bent Right Hand at your cut off Finish but for the normal shot , so to speak, the flail is full , free wheeling , on plane and the Wrists are tension free. Firm grip , free Wrists with a Bent Left Hand past Finish Swivel.... if only momentarily.
Not very many flat left hands post finish swivel out there on the tour.
That said the cure for Throwaway is still the Rolling of the Flat Left Wrist through the ball. Absolutely. As opposed to holding on to a bent right hand. If you Roll the Flat Left you will reduce the throwaway pressures placed upon the Bent Right. Steering is the enemy of the Flat Left Wrist.
Here's a rare discussion on this subject.
