thanks for the replies. I've backed off on the trek 820. I need to look at the fuji nevada1.0, if I can find one to look at, one bike shop recommended it over the others in the nevada series (even though they didn't have any in stock, and did have the nevada3. or4.0).
I've got the hybrid, so if get a mountain bike it should probably be able to do some mountain bike things if I should decide to, not just be another hybrid with fatter tires. I'm going to try to find someone who has specialized bikes. The weight is probably the biggest reason, as an athena (190-200)I'm probably going to be harder on a bike just by riding it than a regular person. My trek 7200 has held up well, but it's nice to be able to take it in to the bike shop for free service whenever I need to, since I can't do any of that myself (yet).
