Struggling With Thumbhole Fit – Advice Needed!

Hey everyone, I've been having trouble with the thumbholes on both of my bowling balls—they feel too big. The PSO drilled them slightly oversized to account for swelling, but I think we went too far. Now, I'm gripping and squeezing the ball, which is throwing off my release.

When I get to the top of my backswing, it feels like the ball might drop, so I overcompensate with my thumb. This is making my release inconsistent, and a few times last night, I couldn’t straighten my thumb in time, causing it to stick and sending the ball flying left. 😖

Would adding tape in the thumbhole or on my thumb help, or should I consider switching to an IT system? I’d love to hear from anyone who’s dealt with this before. What worked for you?

Thanks in advance for any advice! 🙏
