Obviously, there are lots of possible choices for a "dry" lanes ball. Coverstock is most important, BUT you need to know what is "dry" for you in order to determine your starting point in the decision making process. You may need a mild resin, you may need polished pearl urethane or you may need plastic.
I've seen bowlers whine about the lanes being too dry when for them it means they can't use their sanded Goliath. Now, I'm not putting you in that same class, but the point is what ball are using that is hook too much or too early on your "dry" lanes, and are you standing as deep as you can with what you have already?
