I am still in the final stages of testing.
I believe I have found what I am looking for.....(much like Brickguy).
To make permanent lasting and a happy grip change to create the type of hold, release, and roll for MY thumb and hand in the last couple of months.
I Have not bowled much to really cement it(in fact basically virtually none). But I am convinced I am REALLY on to something!
I'll post more soon on this exciting development!
