Track Paradox Trilogy, released in 2016, pairs the QR-10 Hybrid cover with an asymmetric I-Core 2.0 (Dual Density) core. It measures RG 2.48 and differential .057 — low RG (revs up early) and high flare potential, banded on Storm's published scale. It leaves the factory at 1000 grit, polished.
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 Paradox Trilogy appears here.
