I ride with Bontrager Xlite Race 28 mm with MrTuffy strips. Half the weight of the Armadillos and much lower rolling resistance. I am 10% faster for the same effort, and more nimble handling. They have kevlar belt and beads but no special sidewall protection. I have read that the traction is not too good in the wet, but I dont ride if rain is forecast (sometimes I get caught).
