|Storm has evolved one of its greatest balls. This time they are doing so with the Storm Gravity Evolve high performance bowling ball. The Gravity Evolve uses the Shape-Lock High Density (HD) core that has been used in previous Gravity balls. This HD core has a lower RG and higher differential which creates more flare potential. The proven SPEC coverstock sticks to the lane creating a heavy roll and is great for controlling the mid-lane and helping the core to give continuation on the back-end. Scientists say the gravitational constant is universal. This ball could change all that. Colour: Gunmetal/Fire/Crimson. All colors do vary somewhat from the picture shown.
