i have a specialized all-condition armadillo on the rear end of one of my bikes, and a soma everwear on rear wheel of the other. i've always dug the armadillo's. like congereel said, wet weather handling can be a little adventurous, but they last a good while, and i've never flatted one, even after going a couple of weeks without airing them up. i'm still new to the soma tire. i've only had it on for 2 or 3 months, but so far, no problems. the sidewall is thinner, so i have to be more diligent about inflating them, but it does handle a little better, so i feel that it's pretty even.
