I ride in Tucson, AZ in rocky terrain with plenty of loose over hard pack, rocky spots and technical climbs. I started with this in the front for something faster rolling but still Grippy and it worked surprisingly well for the fact that it's blocks are not particularly tall, compared to a Butcher or DHF, though the spacing is not too different. Switched to a Butcher in the front and the Purgatory in the rear instead of the Eliminator and really like that combination. The butcher just gives better grip in the front than the purgatory and the purgatory in the rear has noticeably more grip than the Eliminator that was there before, both with pedalling/braking and with cornering and I have had far fewer instances of the rear wheel sliding out on technical loose climbs. The cornering traction in the rear is also better and I actually have struggled to get it o break loose when I have tried to do so intentionally. The rolling resistance is also not noticeably worse than with the eliminator.
