Just ordered a new vandal on clearance from buddies. Was wondering what drilling would you recommend for a low speed tweener ? I bowl mostly on a THS 39 ft. pattern and usually play around 15 to 5. I would prefer it to be smooth and not jumpy off the pattern. My speed around 12-13 mph. Thanks for any input.

Mine is 65 x 5 x 70-pin under the ring. I absolutely LOVE the Vandal. It is my benchmark ball. I have 3 NIB just because of how it fits into what i'm trying to do on the lanes. Consistent, reliable and I can make it work on just about everything except the extremes.
