I wonder if you're not trying to use the ball on too much oil. I've used this ball a bit, mainly on light to medium-light oil. Mine is drilled roughly 4.5x4, but pin is above & right of the ring finger, quite unusual for me, but it's still urethane and it needs some help in the length department.
Anyway, I've never seen over/under with this ball, unless I was trying to play the oil line. Being pearl urethane, I think this ball needs to see definite dry, even though it doesn't get resin-like length.
My 2 cents:
I admit I have not tried to change the 1500 grit polished coverstock surface it's too good the way it is, for me. But it is a HARD coverstock, as most urethanes are. If I could suggest something, if you're getting over/under (1. try not to play the oil line), sand it to about 600 - 800 grit, then apply something like Resurrection or Clean and Sheen to smooth the sanding lines (on urethane this is advisable), then apply a non-abrasive polish like Snake OIl or Brunswick's High Gloss polish. This will keep that rougher undercoating and the polish will, should, still give you length.
