the shop may be more willing to take the snake back if they get you a LHT frame or complete bike. The smaller frames have 26 in. wheels, and 700 c 's arn't the end of the world. your waight may have a lot to do with the wheel situation. A LHT with Jandd expadition racks, the ft one is a b---h to mount, this would be a fine blue coller touring bike.
