I never tired the Schwababies (huh?), anyway, I use to live in high desert area of California and goatheads that thrive there were tire destroyers. The only tire I found tht work was the Specialize Armadillo All Condition, and they worked so good a tire liner is unnecessary! The Gatorskin failed miserably when goatheads attacked it. Slime tubes also don't work well in high pressure road tires, the pressure of the tire is too great for the Slime gunk to seal before all the air leaks out, if you air the tires up to less then 65psi then Slime works.

Since moving from that area the Armadillos are an overkill, so I switched now to Conti GP4000 with the duraskin sidewall on the Trek and so far so good. I was using Specialize Mundo's but didn't like the way they felt or handled, so right now I've only used the Conti for about 600 miles but already I like the way they feel and handle. By the way, I use no liners and use ultralight tubes.
