Jj,
Do you just dislike the improvised stoves or camping ones too?
dedicated camp stoves like my msr whisperlite are great for a quick water boil for dehydrated meals. Plus some parks not allow open fires I hear.

For survival no fire no smoke, multiple fuels, I think it's a good thing to carry.

The twig stove looks god I wouldn't think a lot of smoke is given off and fuel is plenty.


But you are right nothing beats the flavor and experience of fire/ fowl cooking!
