The twist is that the tire is not going to be used for 100% commuting. I currently have a mountain bike with Kendas (26 x 2.10). I am looking for a thinner tire and not as knobby however I would also like to continue riding my bike on dirt trails (nothing major, as in no jumping off 3 foot ledges, etc.) So I'll probably do 75% pavement and 25% dirt riding. So what is a good tire and what width should I get?

I have read some good things about this tire but I would appreciate some feedback on other tires for my dilemma here.

I am also interested in this tire as well, however $50 seems like way to much for it.
