Storm’s latest Signature line ball features a 2000 Grit NEX Pearl cover wrapped around the Atomic AI Core. I drilled my Physix Blackout 4 x 4.5 x 2 and have thrown it for a few times and I’m quite impressed by it. For a big asymmetric pearl ball it really reminded me of a solid. It was very smooth and didn’t over react when I threw it into the dry too quick. The NEX cover allows it to still handle some oil so I can see this being an overall great ball for a wide range of bowlers and conditions. House shots to sport shots this ball is going to be a must have in the bag because it could be the first ball out of your bag fro the fresh or it could be the second or third ball out of your bag once the lanes start to transition. Compared to my X-Cell the Blackout is smoother and about 4/5 less overall hook. The X-Cell actually created a ton more angle down lane and the Physix Blackout is probably 2/3 feet sooner than the X-Cell.
