What the numbers mean
RG 2.509. That is lower than 37% of the 134 current reactive and urethane balls in our table, so it sits on the high side. Storm says "a high RG ball delays its revving, offering more length and angular motion down the lane."
Differential 0.047. Higher than 50% of the balls in our table. Storm says "a high differential ball will create a sharper angle of entry into the pins."
Hybrid reactive cover. Hybrids mix solid and pearl; Storm says they suit bowlers who need a ball "that can adapt to a variety of lane conditions."
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 Brunswick.
