All advice is much appreciated. For some reason I just don't like the idea of a cat stove and really wish to go with tube/baffle. My wife really wants to keep the footprint small and thinks we should go T4 size. I do somewhat agree with her but if I can build smaller fires in a bigger box for shoulder seasons I feel like I might regret a 1.5 cubic foot box. Either way I really want to do an install thread with pics because I love reading them myself. Thanks to all who chimed in, I like to hear other point of views.
