Super-aggressive traction for when the lanes are drowning. There was no better time to build a big asymmetric ball for medium/heavy to heavy oil — so we did. It starts with our forever-famous MicroTrax Solid cover, loaded with nanoparticles to dig into oil and find traction where other balls slide. After months of testing, the Roto Star Tour block (the “RST” part) inside A.I. Core Technology proved to be the most continuous option — a higher RG than most asyms on the market, which means it keeps moving down lane instead of rolling out. Out of box it's 2000-grit, but tune the surface to fit your game. Who It's For High-oil specialists — when the pattern is flooded, the MicroTrax solid cover finds traction others can't. Rev-dominant players — the higher RG keeps it continuous so it won't burn up and quit early. Tournament bowlers — a benchmark heavy-oil asym you can surface-adjust to match any tough condition.
