I'm curious about the comparison between M-Plus and Nimus Armadillos.

I have the 1.5"x26 Army's and am swithching back to them after an unsuccessful winter on 1.25"x26 Serfas Baristas. Although the Baristas are rated at 100lbs, they seem to gash easily, not just puncture. I never had a minor flat on the Army's in two years - just four very major nail/screw type punctures. I'll give them that.

Compared to the Serfas, the Army's feel a little like rolling on cold water hose. Tough, but . . . well, tough. How 'bout the Marathons??
