I've been having some trouble with my thumb hanging up in the ball. It only seems to happen towards/during the 3 game of league, I'll start to hang up where the webbing meets the top of the thumb causing me to place my thumb only to the 2nd line not quite all the way in so I can still release the ball. Overall sizing of my thumb is fine, I'm just hanging at the top. Should I just pull the trigger and give the top a little more bevel or just use easy slide to combat the hang? Also, is it possible for a urethane thumb slug or thumb mold to naturally get tacky over time even after cleaning it out?

Hope I make some sense and Thanks in advance!!

It's possible, I recently changed thumb pitches in order to get a better grip & have a more relaxed feel of the ball. I originally had 1/8 right 1/8 reverse being left-handed and eventually went to 0 reverse 1/8 left which is where I'm at now...didn't adjust the finger pitches or span when I did this though. I plan on heading to the shop later to work things out.

Ok so you went from a faster release angle to a very slowed one and now you're hanging...logic here dictates you made too much change. I would go back to 1/8 right and zero reverse...you made 3/8" angle change and nothing else...

Yes I found having the 1/8 reverse 1/8 right to be too fast to where I had to squeeze or use a lot of rosin to have a good grip. So I tried 0 reverse, 0 lateral and it was better though I still felt like I was losing it so I went to an 1/8 left and it feels  like it's right but I'm hanging. I'm thinking of trying an 1/8 forward, 1/8 right.

Also, try 1/8" increments at a time so it's easier to gauge...

It's funny.

Most of my ideas on thumb pitches except the Mo Pinel bevel tip (from Mo himself)came from previous postings by Bullred.

I am a big fan of his lots of reverse and lots of palm under for a no thumb type of reverse feel with the thumb in.

I absorbed the "angles" to talk like JustRico who is on the politically correct side of ball reviews.  I do get what he is saying and saying it...."sounds cool".

PS I just was fortunate to have one of the greats in our game show me his latest couple of balls and he noted that it was one piece of tape short.  The pieces of tape were the thinnest slivers I have ever seen.  He seems to think fit is important....hmmmm....

Can somebody please translate any of that^^^^^

Flim flam, boppty bop. Thats what I read.

There's a good point in there . . most of the time when you correct your fit so you don't have to grip, your thumb will shrink, and if you don't keep up with that, you'll find yourself gripping again due to hole size rather than hole angle. 

Go back to 0/0 and make one adjustment at a time. That way you will. W able to tell what adjustment is causing your problem and work from there.

I bevel my thumb hole despite having gone to a relaxed fit. It just feels better to me and causes no problems with my release.

I tend to think that since you are not hanging until the third game that the problem is in your changing your release as you get tired, likely grabbing because your thumb has shrunk, and possibly coming around the ball causing it to lock on to your thumb. I would help to see what is happening.

I'm about to change my thumb pitches thanks to some help from a very helpful dude, and can't wait to change my thumb bevel to as minimum as possible. Enough clearance to get out without having to grab. That's it!

Also, no one has mentioned this, but do you intake a particular food or beverage while bowling? Salt and beer are known to make your body swell over the course of the night.
