nice review turk. that is a nice looking set up.
you're right, the trade off of less insulation would go a long ways in covering the extra weight of the fire resistant material.
i have a friend who has converted to hammocking, but does more hunting than back packing. this may be of interest to him.
the main concerns that stick in my mind at this point are...
1)... the need for a person using this kind of set up to learn & pay attention to the "learning curve" involved w/ the wood stove.
2)... the lack of pitch on the roof makes me wonder if a person in heavy snow might have problems w/ build up through the night (or through the day while they were out doing other things for that mater).
don`t leave the CREATOR out of the creation!
