In bold.
The inside right and outside left of the hand are pressure points only to feel in your grip hand. They are not for applying more spin to the cue ball. That would lead to Back Hand English BHE which is a different topic all together.
At least you gave it a shot.
Thanks
John
I'll read and watch everything you listed and try anything new or revert back to old ideas or a combination of things because I'm suspecting different techniques are required for certain shots and a one grip fits all won't work for me but I don't think anyone is saying that if im not mistaken.
This may not be as easy as I think even though I'm not dealing with mysteries any more and just simple trial and error.
I also have an idea about cue butts that imo is mandatory but I don't want to reveal it exactly but grip location back middle or forward for certain shots has to be paramount if one thinks about it and I don't hear much emphasis on that from my decades in the game.
Thanks John. Back to work.
