Drilling and tools

The Flux weight block has a higher RG to delay ball reaction and create the length needed on light oil patterns.  It also has a very low differential to minimize track flare and provide ball motion control at the backend of the lane.

Sources and method

Specs. Motiv published specs, as shown on BowlersMart’s original Motiv Flux 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.
