Vise blue silicone inserts are a fairly rare secret that in my experience are the best on the market.
They are tough to get hold of and I’ve only been able to get them from Vise staffers and on Bowling Index in bags of 10. Tough to glue into the ball but super long lasting. I have some from 2002 bought from Mike Cimba on this site that are still useable.
I love the feel of the semi’s but you can get them in a variety of styles but only in blue.
All the other grips I’ve tried eventually cut up my finger but these never have.
