Recently made the decision to stop using the Vise lifts, or even thumb slugs, and my game has gotten back to where it use to be before i started using them. I'm far more consistent, have better feel of the ball, and even get more revolutions.
I'm thinking it's that there's more friction between my fingers and the ball itself, versus against the urethane which had a lot of give to pressure.
On another note, I tried a Sarge Easter drilling on a The Thing Lives I had sitting around, and I had so much ease adjusting to the finger differential, it was awesome. Made it easier to change hand position, too, and could go up the back much firmer if I needed to!
Just an all around positive change, and was curious if anyone had the same or opposite thing happen for them.
