GRAVITY EVOLVE

The game has changed and so should we. Stepping back, we realized amateurs and professionals around the world have been clamoring for a heavy-rolling, fast-migrating core akin to one of the most famous of all-time: The Shape-Lock HD Core. This shape can power through just about anything. “HD” is short for high density, which lowers the RG and raises the differential of the weight block. And with SPEC at the helm, expect heavy roll with no shortage of higher scores and more strikes.

The Gravity of the Situation

This shape can power through just about anything. “HD” is short for high density, which lowers the RG and raises the differential of the weight block. A higher differential translates to more flare potential, so every time the ball makes a rotation it exposes a fresh portion of coverstock material to the oil.



Breakthrough Begins

SPEC stands for “Storm Performance Enhanced Coverstock”. The intent behind this formula was to create something that withstands the rigors every bowling ball endures each time it takes a trip down the lane; namely, the friction and oil it encounters. We all know and accept that bowling balls smooth out over time, just like the tread on the tires of your car. With SPEC, you can expect consistent performance that is as tireless as it is dynamic. It’s bold, definite, and extremely potent.

Great ball for oil
The Gravity Evolve is a great ball for heavy oil! It worked best for me as a lefty when the heads are super juicy and the backend is a little dry. I used it in my tournament the other day on a modified house shot after my Halo just faded out. My Gravity picked up sooner, and had a strong backend finish. Took game 5 winner take all with a 279! ??

I have increased my average by 25 pins.
This ball slides through the oil and gaining traction in the last 15ft powering through head pin. With my improvements in revs and control of my release I have increased my average by 25 pins.

Oil Required
If there isn't oil on the lane, the Gravity Evolve shouldn't come out your bag. Monster hook when there is heavy oil! Great first ball out the bag when there is a lot of volume of oil

Great versatility for a big ball
I'll be honest, I was not a huge fan of the Crux Prime.
I was sceptical on drilling the Evolve due to covers being the same on both balls. This ball with my drilling, 77x4x40 creates enough length through the heads and midlane with storing enough energy creating a ton of motion on the backend. This is one of the strongest rocks in my arsenal including my phaze 2 and UFO, just a little cleaner through the heads.
Hope this review helps you decide that you need one of these in your bag.

One Awesome Ball!
I have been seriously learning to bowl for about two years now. I have started with a Nitro 300, to a Storm High Road X, to a Storm CRUX Prime. Then the clouds broke free and light shined upon Storm Gravity Evolve and what a difference this ball. I being a lefty always seem to be fighting the oil pattern from all the right handed players. Well, not anymore! This ball hits the pocket hard each and every time. In the first game I bowled using the gravity evolve my overall average went from the 105's to now 138. I know that I've got a lot to learn and a lot more practice to get me to my goal having a an average of 175, but I'm certain with the Gravity Evolve now in my arsenal, I can see me reaching my goals faster then I thought!
