Not too much to add except to say I'm also pretty short and certainly have short arms but have a LHT. It is the smallest frame they have - (my LBS worked closely with Surly and they all decided smallest was better even though I normally ride around a 48 or 50). The reach on my LHT is better than my road bike - which is WSF. With a Brookes Saddles it is the most comfortable bike I've ever had and I road it across NY state (of course, I don't have a carbon bike so can't compare). The frame size comes with 26" tires and so they are normally wider than road tires.
