Over the past 5 years, I've owned 50+ balls across most of the major manufacturers (Storm, Columbia, Track, Ebonite). I've also dabbled in a few of the smaller player, namely Lane#1 and Hammer. The balls cover the entire spectrum of reaction -- Particles, Pearl Particles, Solid Resins, Pearl Resins, Solid Urethanes, Pearl Urethanes, and Plastics. Cores have been both Symmetric and Asymmetric, with RG values ranging from very high to very low.
I can say with certainty that none of the balls have been duds. There have been a few instances where I did not initially lay out the right drill pattern, or played with a non-optimal surface prep, but one way or another I'd finally get it right.
So I have to agree with tenpinspro. If you have a well developed game and set up any ball properly, it should work satisfactorily on it's intended condition. Having said this, it doesn't mean that you won't like one ball better than another. But that doesn't make the less preferred ball a dud.
