The Gravity Evolve is the second asymmetric ball released by Storm featuring the Spec coverstock. As you may have guessed, the Evolve uses the same core from the ever popular Gravity Shift series from a few years back. The Virtual Gravity was one of the most successful balls in Storm's history so it makes sense to see a new version with such a unique cover like Spec coming to market. Using the tried and true Shape-Lock HD core combined with the hook and control of the Spec cover, gives bowlers a unique combination of board coverage with controlled shape.
I drilled two Evolves. The first Evolve has a layout of 3 X 5 X 1.5 which is mainly intended for use on flatter, tougher patterns. The second Evolve is drilled 4 X 3 X 2, and more intended to be used on medium to high scoring conditions early on while the pattern is still fresh. Using both balls with the box 2000 grit abralon finish, the second Evolve only covers a couple more boards than the 3" pin Evolve, but isn't dramatically different, especially once both balls lane shine. Getting into 1000 or even as low as 500 Abralon, the 4" pin Evolve creates a much more defined move at the breakpoint, as well as about an arrow more worth of board coverage. It is very interesting how close in board coverage the two balls are with less surface, and how much different they are with a lot of surface. It goes to show how important it is to get both the layout and surface correct for a bowling ball. Even at lower grits, the 3 X 5 X 1.5 Evolve has a controlled hard arch to the pocket. This is great for challenging conditions that I want a readable reaction throughout the lane. The 4 X 3 X 2 Evolve does as expected and opens up patterns that are easier and allows me to be less than perfect and still score.
The biggest take away I have with the Evolve as well as the Crux Prime, both balls using Spec cover, is that they aren't going to be big backend hockey stick shapes. The Spec cover creates traction with controlled shape for heavier volumes of oil. The Evolve isn't the typical strong response to friction at the end of the pattern like many of Storm's covers but is a reaction shape needed for hook with control. Thank you for taking the time to read my review of the Storm Gravity Evolve. As always remember to bowl up a Storm!
