What ball is it? What's your style of bowling (rev rate, speed, preferred line)? Do you know your PAP or where you track? Can you post a picture of the ball as it's drilled? What about your other balls? How are they drilled? Where's the pin, CG, or MB?
From your picture, it looks like the pin is over the bridge and the CG is in the center of grip. For most people, that's a longer pin-to-PAP; that layout will usually promote length and backend reaction. If you're a real high tracker, where the first oil ring is very close to your finger and thumb holes, though, that could be a 6" pin-to-PAP (it would be for me), which can be pretty weak unless you have a lot of revs.
It'd be best if we could see what your other stuff looks like and how it's drilled differently.
