If embarking on a tour the first consideration should be "what could go wrong?" If this is to be a loaded tour I would think twice about both frames... One might be a lightweight racing frame with no braze-ons and have to have everything clamped so You'll have to carry spare clamps and it might not be able to fit strong wheels, you really want a good set of wheels... with the raleigh what size of wheels does it take? Will you be able to put a strong set of alloy wheels on it?
