LHTs are great, just make sure you don't mind the whole bar-end shifter thing. Got a Jamis Aurora because I couldn't live with it, have been doing very well for me since. (and even that option's succumbed to the Bar end shifter trend in the 2012 model...)

while we're talking Surly bikes, I saw a Big Dummy parked on the grocery store's bike rack the other day. That thing looks sweet!
