The solid part of the cover is that of the Strike Zone and Ultimate Inferno. The pearl part is that of the original Inferno. The Blast Zone will fit between the two as far as reaction; longer and more angular than the Strike Zone, and earlier than the original Inferno.
So far I have been VERY IMPRESSED with the Blast. On the THS I had more recovery than either of the above-mentioned balls. Miss outside? Who cares! The ball comes truckin' back to the pocket. If you've enjoyed the Vapor Zone and the Red Zone, this ball is a must-have for you. Strong, but not jumpy on the back end (factory finish).
