cyccommute, I don't really understand you twitchy comment. After 10K miles on my 2008 I'm pretty sure it's not twitchy. My frame is a 55 and with 45 sidi's my heal does not strike my orliebs. 45's are size 11 US. Have you had a chance to ride the bike loaded on tour? The bike is more than relaxing.
I don't own a LHT. It may be the greatest thing since sliced bread also. At the time I puchased my Jamis it was the best bike for me for the price. It cost $800 plus tax. Lifetime frame warranty and 1 year on componants.
It's a great bike that will serve you well on a cross country trip. Just like a LHT, T2, and many others.
I haven't ridden the LHT or the T2 loaded so I can't really comment on how twitchy they are
