Keith, have you ever tried closing the #3 grip?
No, I have never used one of those before. I gripped 45 lb plates, DB wrist curls and would hang from the chin up bar with either weight hanging or my training partner pulling on me. I had a pair of grips in my car I used all the time. they were the black handle kind. But I would take off the S ring and bend the ends up then replace the S ring. It would make them 5 times harder. I always had friends try them. I think just a couple could close them or come close.
