Pros: Lightweight and low rolling resistance for a big tire.
Cons: Expensive (but worth every penny).
Recommendation: These tires were on a bike I demoed in St George, Ut. The gave me tremendous confidence on everything from slickrock to hardpack to sand. I could lay into corners with confidence regardless of the surface. They were surprisingly light and had unbelievable rolling resistance for such a big, confidence inspiring tire. It was like the best of all possible worlds in one tire. This is my #1 all-mountain tire for western conditions. Can't speak yet for their wet/mud performace.
