ryguy119, This discussion is getting far away from your initial question. You'd be better off consulting with a good pro shop and/or very knowledgeable bowlers in your area. Your Disturbed, with its out of the box finish, is an excellent ball for medium to heavy lane conditions. After learning what else you have in the bag, you are in danger of turning a versatile bag into one that is too specifically aimed at dry to medium conditions. Also, a 4000-grit, then polished surface is much different than a moderately polished surface on top of a 500-grit/1000-grit underlying surface. You're in danger of turning an excellent mid-priced ball into an expensive spare ball. End of my input. Bowl well and score even better!
