Yes, this is a great conversation! I voted 120-140, although I've only ridden HT for the last 34 years. But probably the best all around bike you could take anywhere is a FS bike. In fact I'm playing around w/ a 120 FS bike right now, and like it so far! I've said before, and for me, I ride HT over just about everything, but the key is I go a LOT slower. I've never felt beat up from it, and prefer it for climbing the fire roads that most of us have to climb on. Trails I'm on 95% of the time are pretty buffed out, and not steep, so I don't need more very often. I'm trying to get more Big Bear Skyline in, as well as get up to Exploration and SART more often to justify my Chameleon (modern geo, 130mm fork). If I find that's not enough, I'll start using the Sector more!!!
