Do you mean the semi-fingertip grips with the hump? If you are using those, I would keep them & add maybe 1/4" reverse. Also, if you are stretched, you may want to drop it slightly. I had the same problem with my ring finger so I shortened the span & added more reverse. It has only slightly improved, but it's not getting worse & I can still bowl, so it was worth the change.
