Titanium is nice light stuff, but not good if you want to do real cooking (as opposed to boiling water to rehydrate dried meals). It doesn't conduct heat nearly as well as aluminum, so you'll have burned food over the flame and raw food elsewhere. If you're going to cook, consider anodized aluminum instead; it's only a few ounces heavier.

Of course if, like me, you're only boiling water, titanium is a bit lighter. The rim of the pot cools off faster, so I can drink my tea out of it while the tea is still hot.

One of the reasons I take a small multitool is that I can use the pliers as a pot lifter. I need the pliers for other purposes anyway (I don't have a lot of grip in my fingertips), so I have them along regardless.
