The Storm Zero Gravity is the latest release in the Premier line for Storm. This ball utilizes a new coverstock formulation that is a solid version of the ERG coverstock that was used in pearl form on the Lucid and Byte. This new cover surrounds Storm’s new Shape-Lock LD weight block. This core takes the basic shape of the Shape Lock core in the Virtual Gravity line, but with a much lower differential (LD).

This ball’s lower differential reduces the flare and it was best for us on the medium test pattern. Cranker liked this ball best on this pattern and for good reason. He was able to hit the ball as hard as he wanted at the bottom of the swing without it hooking too much or going sideways at the breakpoint. Even as the pattern broke down, he was not forced left enough to have to...

The Zero Gravity is pretty smooth for a Storm product. When balls like the Byte are too angular at the breakpoint, switch to the Zero Gravity.

The 4000 Abralon finish accomplishes two things for the Zero Gravity. It allows the ball to bite through some oil and the sanded finish smooths out the back end reaction.
Back End
(1-20)
15.5
The back end reaction is less than most other balls with the Gravity name. The new Shape Lock LD core’s lower density and corresponding lower flare potential is what reduces the back end movement.
Total Hook
(1-100)

The total hook on the Zero Gravity is less than the Marvel-S, but more than the Byte. Higher speeds or lower rev rates will have more success on medium patterns.

Strengths: A lot of times, bowlers are restricted to using high performance balls solely on heavy volume patterns. The Zero Gravity is versatile enough to use on most medium patterns as well.

Weaknesses: Bowlers looking for a ball to cut through oil on really high volume patterns will need to drill this ball very aggressively. Adding more surface will also help on these patterns.

Overall Summary: The Zero Gravity takes very well to surface changes. Higher finishes will allow this ball to store more energy than it does at the box finish.
