Highroller/Minion is pretty common at BC as long as you run dual ply and at least 2.5's. It's amazing just how harsh that place is, even compared to Nat'l or Holbert. It's one of the only places I've gotten pinch flats on both front and rear tires. Ghetto tubeless works quite well for that though...Another tire combo to check into is GEAX; Neuron front, DHEA rear. The DHEA wears a bit fast but it's cheap enough. Sidewalls are very thick and they have lots of air volume.
