The Apocalypsetm marks the end of average bowling! We've taken the best characteristics of the Cyclotron II tm core along with a totally new Rev-elationtm reactive coverstock giving you the ultimate performance on those medium oil patterns. The Rev-elationtm coverstock combines the best properties of solid and pearl reactives. Our extensive testing has shown the strong mid-lane traction of a solid reactive combined with the sharp backend motion of a pearl reactive. A new world of ball reaction awaits!
