Hi Barry,
Does ‘neither’ count?

I use Heet since it is easier to light in sub freezing temperatures than denatured.
I barely notice any difference in efficiency between Heet and denatured even though denatured has a claimed more btu/weight.
I also won’t use rubbing alcohol again <img src="/forums/images/graemlins/tongue.gif" alt="" />: It doesn’t leave your pan clean; it leaves water in your stove (and thus precious stove fuel volume is reduced). I don’t know if it’s finished (in broad daylight) because there’s liquid still in the stove! It’s heavy for given burn time, and takes up too much room for given burn time. I have no health issues with Heet since I don’t touch the stuff. And even if I do touch it, I have to swim in it to be a risk. As a side note, I would rather have Heet leak in my pack than petroleum fuel--- so that’s a safety plus.

Maybe I should buy stock in Heet <img src="/forums/images/graemlins/smile.gif" alt="" />
