Saw, what is this "Space aged" grip that you keep referring to?
I use the IBPSIA guidelines that I was taught over a 2+ year period by Ron Hoppe himself. I surely know that I am NOT hurting peoples hands. And yes, I don't use near as much reverse as I used to 15+ years ago, and do use some forward. Pretty sure Bill Taylor's book is still a good guideline.
The game, equipment, and lane conditions have changed from the "Urethane Release" days. We (my coach and other coaches that I know, and myself) don't teach the grip it and rip it "urethane release" style anymore. Loose armswing with a consistently repeatable release is what I'm after. You cannot teach this with more reverse than the player's span and flexibility will allow. Add in that many bowlers use their thumbholes too big, and you have bowlers that are squeezing the ball. If you use less or the proper amount of reverse/forward pitch, then you can have a more free armswing and still have the thumbhole a little big.
If you are still using a stretch fingertip grip, then of course you have to use plenty of reverse thumb pitch, or you will be locked into the ball.
One of the things you seem to be forgetting is grip pressure by the bowler. If he/she is squeezing the ball, and the driller is unable to teach them to stop squeezing, then more reverse pitch will let them squeeze it and get out of the ball. BUT, ultimately the problem is not fixed. The bowler will not improve in the long run, and you as a driller, did not help them.
Carol Norman gave me the phrase "you cannot out coach a bad fit". This is so very true.
Chris Barnes uses a relaxed fingertip grip, does have the ring finger dropped slightly, but doesn't use excessive forward pitch, does use his thumb hole extremely tight.
I saw Pete Weber this summer in Arkansas, his thumb pitch does look to be about 1/4 reverse, with little or no lateral. Not much bevel on this thumb and pretty much a round hole, made slightly oval with tape. 1/4 reverse is not very much reverse considering he has about a 5 inch span. I also have one of his balls (Bolt Pro) autographed in my shop, his grip looks the same as it did 3-4 years ago. Don't think he is using lift grips as he wears the golf glove over his fingers, think he is using Vise Oval grips.
Saw, pull your head out and try to have a little more of an open mind. There is no absolutes, only what works for a particular bowler.
