I currenlty roll a hot rod pro stock, and pro stock pearl. Both balls are about shot and I was looking into getting a new reactive and spare ball. For the reactive I was looking at the two listed in the title. I like storm balls and have had good experiences with them in the past. I checked storms website and they had these two listed for me with matchmaker. Could someone tell me whcih ball would be more effective for me. I'm a tweener, 17 to 19 mph, high revs, high axis. Lanes are light to medium depending on the night. Please give me some advice on which to buy. Also, anyone know of a good cheap spare ball to buy. I've seen some of the team storm balls, do they react at all? I've never had a spare ball, and I need to get this one to pic up ten pins mostly. It seems to be the only pin I have trouble hitting. Thanks in advance. Kyle
