Titanium vs Aluminum
if all the Scouts are doing is boiling water, Titanium is OK. But if you ever foresee them wanting to cook a thick soup, or cook up a freeze dried meal in the pot, or do real cooking in the pot you are better off with aluminum. Titanium does not have good heat dissipation and is really nasty to cook with, very easy to burn the food.
While snow camping, despite my best efforts, stove on low, having the Scouts constantly stir, and use of a scorch plate, my very nice 4 liter Evernew titanium pot burned up on the bottom while cooking up a potato bacon cheese chowder.
