I'm rocking a 2004 T800, but upgraded the components with old road 9 speed road components from my race bikes. The freakin bike rides like a dream. I commute daily on it and I also took it down the entire California coast last year with absolutely no problems.

For the tour, I used 700x28 contintental top touring tires, a way overloaded bob trailer and way overloaded front and rear panniers too. Again, no issues with the additional weight (except that the tires did wear down faster than I'm used to). The beast was as steady as ever on the long descents as well. As others have mentioned, it's definitely much more stable and forgiving when it's loaded.

I'm a minority in the forums weighing in at 130 lbs, but I've had no issues with comfort at all, so I can't comment on others' views about "bigger is better" in terms of comfort. I don't think you can't go wrong with the T800 or T2000.
