Storm · Premier line
The Storm Alpha Crux is an asymmetrical solid bowling ball from Storm's Premier line, released in May 2026. It has the GI26 Solid coverstock and the Catalyst AI weight block, finished at 2000 Grit out of the box. At 15 lb its RG is 2.48, with a differential of 0.053 and a PSA of 0.018.
Among the 65 balls here with a 15 lb version, its RG is low, so it revs up early, and its differential is high, for more flare. Its reaction ratings suit it to heavy oil and medium to long patterns in fresh conditions, with an early hook, a smooth to moderate turn at the breakpoint and high flare.
