Storm Bowling Ball Core Library
Every symmetric and asymmetric core Storm has put into a ball, in one searchable reference. Click any core to see its specs, the balls built around it, and the layouts that bring out its best motion.
Symmetric vs Asymmetric Cores
Before you click into a specific core, know which type you are looking at. The distinction changes how the ball lays out and how it moves on the lane.
Symmetric Cores
Have only a pin marker. Produce smoother, more predictable motion. Easier to control and ideal for benchmark layouts and arsenal foundations.
Asymmetric Cores
Have both a pin AND a PSA (Preferential Spin Axis) marker. Generate stronger, more defined backend motion. Standard in modern flagship balls.
For the full breakdown of how cores work, visit the Bowling Ball Cores research hub.
