If you have problems getting the ball to the pocket because of oil, then I would go with a proactive (particle) ball. I have heard nothing but good things about the Shock Zone,
Brunswick's newest ball. It would be best to talk to your local
Pro Shop to see which ball would work best on your house lanes. Personally, I have switched from
Brunswick equipment to
Columbia equipment. A good med to heavy oil ball is the Rock Star, or the Rock On for a little heavier oil condition.
