The new Purple Solid Reactive is an exciting and unique ball, just as the Purple Pearl Urethane ball is. The Purple Pearl Urethane ball sells because it performs, and there's nothing like it in bowling; the Purple Solid Reactive will be successful for the same reason. The new Purple Solid Reactive started as an experiment to see how a strong reactive shell would perform around the high RG and low differential LED core, and the results were remarkable. The core is the exact same as the urethane model; however, the numbers are different due to the density of the reactive shell versus the urethane; this raises the differential and creates more flare, producing a stronger and more angular backend motion. The Purple Solid Reactive will be useful for bowlers who find urethane too weak when others are scoring with it, and higher rev players will love it across a wide range of conditions.
