If you end up in a lot of out-of-the-way little towns you may not always be able to find butane cartridges. A multi-fuel stove that burns white gas, kerosene and alcohol may be a better choice. Also, for cook pots, on long trips I prefer a 1-L titanium pot with lid over the smaller solo pots. Water actually heats faster in a larger based pot and I use the pot for washing stuff. Think about making insulating "cozies" for your pot and cup. And be sure whatever stove you have has a good wind screen - really makes a difference in saving gas.
