I didn't get the ball yet. But I heard people saying it....I'm on the fence with this ball. Havnt used storm in a long time.
People who do no ball maintenance (cleaning AND refreshing the surface) will always suffer the worst loss of performance. All balls will lose some performance even with diligent maintenance. Some coverstocks just absorb more oil, some people bowl on more oil, rougher surfaces absorb more quickly, etc.
So some balls need oil extraction every 200 games some need it every 25 games. ALL ball need surface refreshing regularly, sometimes as frequently as every set; sometimes as long as 25 games; it depends on the circumstances.
Rich or lazy people need new balls every month ....
I'd only worry about Storm coverstocks if you worry about every manufacturers' coverstocks. Storm is no better or worse than any other brand (except maybe Lane Masters and Visionary; Brunswick may be entering this realm, not sure yet). So if you're on the fence about buying a Storm ball, you should really be on the fence about buying a bowling ball at all.
