E.J., I know this is sort of irrational of me but I've never used non-stick pans (while camping or at home) since I learned what Teflon was first invented for: it was used to coat piping that transported radioactive material in the Manhattan Project.
It may have the lowest friction coefficient of any material known to man, but it has no business near my food. ;)
Another thing: I'm a public health researcher and I can't help but notice a bias in the research related to the health ramifications of using non-stick stuff. If the reserach was independent, then the conclusion tends to be that teflon is associated with health risk. If the research was funding by an organization, however tangentially related to the sales of Tefon products, then Teflon is safe.
Another thing: if you get a pet bird, vets instruct you to stop using teflon pans because, if you overheat them, they release toxic gas that is especially harmful to birds. Think canaries in the mine shaft.
And titanium, with its poor heat dispersal qualiteis, will definitely create hot spots that overheats the coating.
Scratched Teflon is especially risky, and it's tough to clean pans in the wild without scratching them.
It's just bad stuff dude. Life isn't convenient. Crud sticks to pans. Teflon kills. Play it safe. ;)
