I'd be curious to hear more about the ''unhinging.'' ... Is this the action of the wrists, and when does it occur?
"Unhinging" is not a perfect description of what the wrists do when you swing.
If you are familiar with pitching, you will know what IR is by now. I find it very close to the twist of the wrist, except in he opposite direction, when "turning the barrel" ... and then the "serving the Pizza' wrist action, through contact.
My cues are mutating.
I worked on this last night at practice. It went heavy bag, tee , front toss. all the same movements at each station.
start of drill
twist back to slot
rock the u at this point in the sat position, coiled on rear hip.
