Well I'm currently looking for a new ball, the lanes I usually bowl on are a high volume house shot, I've been throwing a storm virtual gravity for a while and its got quite a few games on it. I've really liked the ball overall.  I've really started to notice the decrease in performance over the past 6 months, isn't moving nearly like it used to. The only other ball I carry with me other than my spare ball is a rotor grip Mars which I hardly ever get to use due to conditions. I've been looking at at the rotogrip mutant cell Pearl, any other suggestions?
