Storm Gravity Evolve
Storm continues to evolve the game of bowling. 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 cover stock sticks to the lane creating a heavy roll and is great for controlling the midlane.
