Does material matter to you? You've got different materials on your list: Soma (cromo frame and fork), Jamis (aluminum frame, carbon fork), Tricross (aluminum frame, carbon fork) and Kona Jake (aluminum frame, steel fork).

From everything I've read, people seem to prefer to tour on a steel frame. From your list, I would pick the Soma. However, I can't imagine you'd go wrong with a Cross Check (I have one and I love it). By the way, I have yet to hear, read online, or experience anything negative about the Cross Check.

Good luck!
