Are there any drills that I can work on to help me ingrain the feels of pivot lag, as well as maximum power and trigger delay (I think I may have one for the flat left wrist)?

Aaah, Component Translation...the heart and soul of the Star System of G.O.L.F.! Mechanics produce Feel, and Feel reproduces Mechanics (1-J).

There are plenty of ways to Translate precision Pivot Lag and Power Mechanics into their Identifiable Feels. In fact, they are limited only by one's imagination. Off the top of my head, here's a Starter Kit:

1. Use a mirror and imitate the photos 9-1-6 through 9-1-12 in TGM. Also, photos 9-2-6 through 9-2-12.

2. Do plenty of Start Down Waggles. Feel your Lower Body lead and your Upper Body lag. Also, feel your Left Wrist Cock more in the Start Down.

3. Imitate the left-handed dowel 'baton twirl' I do illustrating the Sequenced Release (Uncocking Power of the #2 Accumulator and the Overtaking Power of the #3 Accumulator) in The Gallery video "Are You Prepared to Roll On That Line?"
