I rode a specialized last year to compare to the Trek, and I didn't care for it. I might feel different now that I actually know what I'm looking for ... but I'm strongly leaning towards renting the Klein tomorrow and trying it out on the trail, then applying the price of the rental to the bike, assuming it works out, of course.
It sounds like the woman who did this is disputing the matter ... I'm not going to wait several months to get insurance payment.
