I like it. It is perfect as an original conception.
I assume it packs like a dream and is fun to put together.
That said have you checked out the Nimble Will Nomad stove?
I notice your construction technique is similar.
I like your tall narrow shape. Better for convection and heat reflection creating a cleaner, hotter burn.
The one thing you might take from the Nimble Will design though are the notches on the top. They make superb places to put stakes to improvise a grill if you wanted too.
FYI, I also agree about the weight. It's a little heavy considering its size though you might consider some design modifications if you did want to go to titanium.
I assume much of the weight is because of the design. I.E. the tops of the plates holding up the pot need to take considerable weight and hence need to be sufficiently thick.
If you can get enough airflow through the nimble will style notches or by putting additional holes beneath (or by some entirely different and original approach) then your pot support will be more stable and you'll be able to use thinner metal.
Of course what's a couple ounces. Ease of use, enjoyment, well packing. Like I said, it is in a way perfect in its original conception.
