Ebonite Game Plan, released in 2010, pairs the Traxion Reactive™ .039 cover with the EMP-1 core. It measures RG 2.51 and differential .058 — low RG (revs up early) and high flare potential, banded on Storm's published scale.
Measured at 15 lb. These are box specs for an undrilled ball — drilling changes them.

These specs are factory reference for the model, compiled from manufacturer publications and other sources and provided as is. They may contain errors or describe a different production run, and they say nothing about the condition of any individual used ball — surface prep, resurfacing, plugging, and drilling all change how a ball behaves relative to its published numbers.

The Ball Finder matches your rev rate, speed, and lane condition against these specs. Buy and sell used on ReRack — your payment is held until the ball is delivered.
Closest on the three specs that compare across brands — RG, differential and symmetry. One ball per line, so no other version of the Game Plan appears here.
