I don't own an Atlantis, but I'd be very interested to hear how these things ride on pavement compared to the Antelope Hill -- or to the magical 60 mm Schwalbe Big One, in the 450 gram model.
I ask because while the Big Ones roll on pavement like the best road tires I've used, they obviously require careful cornering in loose dirt, including crusher fine-surfaced trails, and I wonder if the Fleecer Ridge will roll very well on pavement while providing more cornering grip in sand and on crusher fine.
