First, I think the flat left wrist/bent right wrist concept.
Then the confirmation and focus on each of the pressure points in the hands. I found the more downward I pressured the shaft with 1 and 3, the better the compression. Like City says, "straight to China."
Then the concept of the Power Package and dumping it right down through the ball.
I think those for starters and that's without much thought. Others could very well add and of course correct me here.

All that is good. You found some new feels. And learned something about the geometry and physics involved.

But did you strike the ball better after doing the basic motion practice? Longer? Straighter? Better trajectory? More FIR's and GIR's?
