pitching your fingers to the right (if you are right handed) will shift the ball more on top of your index finger. It will also possibly lower your tilt (and possibly raise your track). Most no thumb bowlers have a very low tilt and high track now.
If it were me I would try Mo's generic grip for a no thumber:
middle finger=7/16 left, 1/4 forward
ring finger= 7/16 right, 3/8 reverse
Thanks for the reply. Yes I can see how since my track is high now, right lateral would make it track even more to the center of the ball. I'm not sure on my terminology but my track is close to the fingers and thumb (thumb hole is in a normal location) but hits neither. I do think it has a very large diameter.
About Mo's generic grip: What is the reasoning for the forward pitch on the middle finger and the reverse pitch on the ring finger? I'm sure I could search out the answer too. I'm just taking a short break here at work.
One more thing I just thought of: If I did try the right shift and it did raise my track, why would that be a problem provided I didn't track over the holes? I mean if I'm not hitting the holes now the track should still be the same distance from the holes after the change, even though it would be closer to the center of the ball. Or am I wrong? I guess I'm thinking the thumb hole might have to be adjusted right as well.
