Chaotic Core gives me consistent axis migration, defined RG bands and the freedom to unleash as much or as little anarchy as you please. The new Chaotic Core boasts a medium RG with a High Differential/Mass Bias Differential that reads the midlane with an angular motion. This earlier read makes it a great ball for fresh, dense oil but still maintains the versatility to play later into the game.

Sources and method

Specs. Roto Grip published specs, as shown on BowlersMart’s original Roto Grip Chaotic core page (2022), as published by the manufacturer.

Baseline. The baseline is 265 in-stock, published reactive and urethane balls. Plastic and polyester covers, 2-piece, 3-piece and pancake cores, missing covers and missing RG or differential values are excluded.

Percentiles. Percentiles are the share of baseline balls with a strictly lower or higher value; ties are not counted.

Nearest cores. Nearest cores are ranked by distance on standardized 15 lb RG and differential, with the same symmetric or asymmetric shape preferred among near ties (distance bands of 0.1).

Mass bias. Mass bias is compared among asymmetric balls with numeric mass bias only.
