Another + for the Road Morph. I wouldn't waste time with another pump for touring. It has a small inline gauge, a small foot pod and a nice hose so you won't be pumping directly on your presta valves. It might not be the smallest thing but small pumps are a pain to use and make getting to higher pressures even harder.

If you really can't imagine getting a well reviewed practical portable pump that is perfect for touring, then I would suggest one of the Race Rockets. They make a carbon version and they have a nice hose that extends and tucks away when not in use.
