This is hard for me since I change out my equipment each week. I do this to keep all balls in my library fresh!
But my, "get-me-out-of trouble" ball this season has been my Storm Prodigy. I have used it on light oil, medium oil, and medium heavy, successfully. Most of my equipment is pin down, to keep it from jumping on the backend. 288/735 in a tournament with it this year!
I also have a AMF Hawk that is rico drilled and a benchmark piece for me.
