JoPo Inner Thumb Slug Drilled

Buddies drilled 2 inners for me based on 2 Turbo SwitchGrip inners I sent them over the summer. My thumb size changes a lot & I don’t like using tape. I asked them to drill me a new inner “a hair smaller front to back” based on the smaller of the 2 previous inners. Well, with that minimal instruction, they did the new inner and it’s perfect! Can’t recommend them enough. I just ordered another for my spare ball.

Love these inserts - keeps the feel of each ball consistent vs a different feel every time you grab another ball. Excellent product!

The JoPo thumb system is the most secure, and best feeling one Buddies drilled mine, fits perfectly like everything they've done for me. Can't recommend them enough

This is a great addition to any bowling ball, especially having the ability to keep the thumb hole consistent ball to ball. This is the 3rd ball from Buddies with a Jopo slug. Will not be going back to traditional! Easy to install/swap.

I am Pro Buddies anyway and the fact that Fell in love with JoPo thumbs and Buddies made a mold of my thumb and it comes out perfect unreal fit and gives so much control of your bowling ball, love it,,,

First time going to a interchangable thumb - Extremely happy with the product and performance. Solid construction and love the screw in feature.

Good product consistent thumb fit
