Numbers as Storm publishes them, checked 21 October 2026. Storm doesn't say which ball weight these numbers are for. Drilling changes how a ball behaves, so a pro shop's layout matters as much as these numbers.

What the numbers mean
Polyester cover. Polyester (plastic) is the cover used for spare balls and house balls: it grips the lane least, so the ball goes nearly straight. See our plastic spare ball review.
Symmetric core. Storm says symmetric balls have "RG values consistent across all axes" and a smooth, predictable roll.
USBC allows an RG from 2.447 to 2.813 inches and a differential of at most 0.060 inches (Equipment Specifications Manual, March 2026). Our ball spec table lists every current ball we track, and who makes bowling balls covers which company owns Storm.
