1fife, here are some suggestions..
1. Because you're hitting on the front left of the thumbhole, you will usually need more right pitch. You can also try more reverse pitch, i.e. 3/4"
2. The span is slightly too long, because you feel the front edge of the hole as you're putting your thumb in the ball.
3. Because your thumb is short, stubby and not very flexible, I would think that your ring finger should be shorter. Place your thumb in the ball, then lay your fingers over the holes. Then measure the distance from the front of the hole, to the crease of your finger. You want the distance to be the same for both fingers. The crease should almost be in the center of the hole, but probably just before.
Let me know what you come up with for the distance of the crease to the front of the hole for both fingers.
4. You will need more/the proper bevel. Bevel is the most important thing concernig a thumbhole. Try beveling down deeper inside the hole, and taper it out towards the top like a funnel. This will allow your thumb to go in deeper, but also come out without hanging.
Keep beveling the ball, wherever you're hanging, until you don't hang anymore..!! Then, tape up the hole on the front and backside, until you're able to hang on to the ball without squeezing it too much, while also being able to release the ball whenever you want to without hanging.
Do whatever you have to do to get rid of the hang, as far as reverse pitch and bevel goes. You say you're using a lot of bevel, but it probably is beveled properly.
So, my recommendation is to use 3/4 reverse, 0 lateral pitch. Let's start out with alot of reverse, so you can clear the ball. It's better to exaggerate to the extremes, so you can feel the difference and get the desired effect. Then, you can cut back on it later if you want.
Also, I'm guessing that we'll have to shorten your ring finger to 4 3/16. This should get you out of the ball along with some bevel. After you're clearing the ball cleanly, you can start to reduce the reverse pitch and bevel to where you start to hang again. Then, you'll know where you should be.
There's nothing wrong with using 3/4" reverse pitch, it's only a number and may be what you need, depending on your thumb and how you want to release the ball. =:^D
