Thanks guys appreciate the input.Had the ultimate it was ok but due to my low amount of tilt and axis is was very condition specific.  Very Strong cover solids or particles I have a tough time finding the right one to carry. I have had 2 OI's and 3 v2's but not the gamebreaker so thats why i asked about that. Bob have you done anything to the cover?? Very interested in the ultra but not a big assymet fan.

You can't go wrong with the OI, AI, or Ultra Zone. They are all great balls but they excel on different oil volumes. I'm finding less and less uses for my equipment with the original Activator covers as the oil volumes have increased, and I'm not seeing much shot breakdown with the type of events I bowl. As much as I liked the OI and still like the AI, the Ultra Zone is even better. There isn't much else like it - it's a great core/cover combo.
