With six exciting colors and innovative fragrances, the Tropical Storms are sure to appeal to bowlers of all skill levels. They all feature a proven Reactor Reactive coverstock material that glides easily through the heads yet reacts down-lane to provide optimum pin carry. The Camber Core’s inverted light bulb shape has real substance. It provides more predictability and control; it’s the perfect complement to the rest of Storm’s full line of products.
