Storm Proton Physix 15lbs

Proton PhysiX is one of the heaviest hitters Storm has built. The asymmetric Atomic core sits under a NeX Solid Reactive cover sanded to 2000 grit, a combination aimed straight at the freshest, heaviest volume you will see.

At 15 lbs the Atomic core measures a 2.48 RG, a .053 differential and a .017 intermediate differential. Low RG means it revs early, the differential means it flares hard, and the intermediate differential gives the ball a strong preferred spin axis your driller can use to shape the reaction. The 2000 grit solid cover grabs the front of the lane and keeps the ball on-line through the midlane rather than letting it skate. This is not a subtle piece; it is the ball you open with when the pattern is drowning everything else.
