Play with Fire! A disciple of two of the hottest performance balls in bowling, the new Pyroâ„¢ is a perfect fit between the Storm Diabloâ„¢ and Fired Upâ„¢. Combining the proven Twin-Vâ„¢ weight block with a thick Reactorâ„¢ pearl particle coverstock, the Pyro moves smoothly through the heads and provides optimal mid-lane friction producing superior backend motion on longer oil patterns. If you like to play with Fire, you're a Pyro-maniac.
