had a look at Luczak. A bit rambling, but you are right, he is advocating the type of swing I am working towards. Thanks for the pointer.
One idea got my attention. He describes his swing type as an underarm, not an overarm, throw.
The point of that is not so much to do with the arm, but the body sequence. The natural sequence for an overarm throw starts with the body, whereas for an underarm throw it starts with the arm and the body follows.
When I "heave", that is an instinctive overarm throw type body sequence attempting more power as if attempting a long overarm throw. I don't do that very often these days, but I found it helpful to have it explained where that heave instinct comes from.
It remains to be seen whether adopting a general feel of an underarm throw is helpful. I suspect it could be. I have found time and again that a feel of "stay turned, start with the arms" works better, which is the same sequence as underarm. The question is whether "underarm throw feel" generates the better natural pivot sequence I want.
Per your point about contradictory advice, I now have at least 3 "either - or" classifications.
From TGM, there is the hitting or swinging distinction, based on different leverage models
From Hardy, there is the RIT or LOP release distinction
and now, underarm or overarm body sequence
Somewhere in there seems to be the reason you can get opposite advice in two pages of the same golf magazine.
