Nightmare is just that a NIGHTMARE for other ball Mfgr. I'm throwing this on Main Street in a house where the panels are hard. The Nightmare is drilled at a 40 Degree angle. I find that this ball requires oil front to back and side to side, does not like dry, coarse not this is out the box, I imagine with surface change it would react better on the dry part of the lane. But I have other DV8 equipment for that. This ball is a most of you are have troubles getting a reaction on oily lanes
