I use a lot of older resin balls on dry lanes. Currently I am using a 1997 LT-48 Gold on lite volume lanes, as well as an old Brunswick Fury on mediums. On dry, it's Sonic -X's; Ultra-Sonic; and a Scout Reactive.
I could never use my Black Nighthawk for anything but mediums or heavier, because I have too much hand, and my Nighthawk hooks!!
