Pros: Low rolling resistance, good for cornering.

Cons: Sucks in loose conditions (sand, mud).

Recommendation: I don't actually own these tires but I am a big fan of what we used to call "Semi-slicks." The tread in the middle is gone leaving knobs on the edges of the tires to grip in the turns. I run one of these on the front and a normal grippy tire in the back for most of my East Coast rides. At a place like Slickrock you could rock this tire in the front AND the rear for extra speed.
