I just added a second Specialized to my really small stable. I have a Ruby Expert that just flies (or rather, I make the attempt). And I just picked up a Safire MTB. Good bikes. Not that Trek is bad, really. You have to be comfortable on the bike; it has to fit. Try both and pick whichever feels best.
