Bill, that is an excellent link to the supercat/simmercat specs and discussion. The author really put some work into it.

I used to only cook over fires until about 1982 or so when I received a Svea123 as a gift and started using it . As long as you are not trying to really crank out the miles (and it's legal and you have a ready source of fuel and you are good at starting up wet fuel...), this can work out well. So, I've been intrigued with the wood burning stove designs that have been coming out the last few years. People are getting pretty creative with this and I think it wont be long before a relatively light design comes out. Again, this all depends on where you dive into the backcountry but this could be worth looking into. There is so much traffic in the Sierra that I decided long ago to stop building fires there unless the people I was with wanted a fire (and was legal). But in other less traveled areas....
