Maybe I'm a little dense...
From the OP
I plan on camping each night with a small tent, and travel rather minimally.
I interpret this to mean he's more concerned about his weight not the weight of his gear. Does he really need a tank of a touring bike to accomplish what he's trying to do or would a "sport touring" bike with decent wheels fit his needs while providing something a little more fun to ride after the anticipated 10 days of light touring are finished?
I see bikes have been narrowed to the LHT and 1.1. Between those two I'd take the 1.1 as you get more for your money but having been down this path in the past and having chose the Randonee if I were doing it again I'd buy something a little more sporty and focus on solid wheels, unless of course I planned on carrying the kitchen sink with me then it would be the Randonee (aka 1.1), Marrakesh or Advocate Cycles Sand Country...
