It seems like your not set on a certain company like I am... (storm lover) i'll try and set a few basics for the companies that i like. Being that Roto and Storm go hand in hand i'll list a few off that i've had success with. The best ball for that i've thrown for these conditions would have to be the Roto Grip Venus. Easily the most underrated ball for these conditions that i've seen. The out of circulation Spit or Sure Fire would be a great ball too. Anyways these are my balls that I would go to, but these are only my choices and there at many other balls to go to.
