I diagonally read through the first page of the thread... and I would like to add my (limited) point of view. No matter whether open fires are allowed or not in the area, a stove is always going to be more efficient for cooking than a fire. Cooking something in a pot, that is, not roasting a whole pig over a bed of coals.
There are stoves that weight 25g (such as this one, which I own,
BRS-3000T) that paired with a 100g gas cartridge + the pot that you would be carrying anyway gives you the choice of brewing in the middle of the worst weather Apocalipsis... Even if you don't use it as the main cooking means... you could always use it to boost start your wood bonfire. Not the first choice for melting buckets of snow to get water but for noodles, soups, freeze-dried food is ok.
Even if you plan your outing arround wood fires... 125g is what an Spyderco Endura goes for (more or less). I bet some guys carry more weight in firemaking gadgets such as dry tinder, fatwood, fire straws, solid fuel tablets, etc. I think it pays off...
For me, wood fires are something else to worry about and are, as anyone would expect, a fire hazzard. I don't want my down filled sleeping bag (ultralight synthetic fabric) anywhere near a fire where a stray spark may burn a hole on it. Same goes for fleeze jackets, Scholler fabric pants, Gore-Tex third layers, gloves/mittens, backpacks, etc. In my opinion, to be safe arround fires, you need to go old school and wear cotton, wool or leather. Same for the sleeping setup. Old school gear is much heavier and less efficient (sucks up water, insulates less, more difficult to dry, etc). So for me, I preffer to go synthetic, light and do not rely on fire to keep me warm.
Maybe my needs are completly different than anyone elses here but... fire for me is something to avoid is possible. If something goes really REALLY wrong and I find myself in an emergency situation, you bet your precious that I would be setting the whole forest in fire if required. I get it is a great moral boost but I preffer to do without.
