I have a 15 lb storm vertigo that is on it's second drill. My pap is 5 1/2 over x 1/3 up. The ball is drilled 4 1/2 x 4 3/4 pin down with a 1/2 inch weight hole 3 inches deep 1 1/2 inches below mid line. The problem that I am having is that I am more so a medium speed bowler, and with this ball and how it is drilled, it obviously flares quite a bit and roles nice, but snaps on the backend. Adding some surface does help but then it doesn't quite role right on any decent amount of oil.

Since I can't really sell this ball because of the second drill, I was thinking of plugging it and putting a different drilling on it. I still want it to be pin down, like a 5 x 5 1/2. What other drilling suggestions would you guys recommend? I have a deuce that is drill 4 1/4 by 4 1/2 pin next to ring, weight hole 4 inches over on mid line. I want this vertigo to be slightly stronger over all in the oil as the deuce roles nice and smooth.

I have around medium revs and can vary axis tilt and rotation.
