hate to bring this up, but gearing wise, if you ever do loaded up touring, you could easily end up carrying 30lbs of stuff, and it seems to me that all the bikes mentioned will be overgeared, 50/34 cranksets, and then we dont even get into the wheel sets-not really made to be carrying a lot of weight on the back wheel.
just a couple of important points to take into consideration, although if you have never done touring with panniers, unfortunately you won't have personal experience to know how these two things will affect things.....
