You get a reasonable porch with the Photon but the Photon 2's porch is only 25cm deep. I haven't had to cook in mine yet but I'm dreading when I do as it seems like the stove would be awfully close to the outer.

A bit, but I think so long as you're using it in the porch with some ventilation you should have no bother. From memory the Esbit blocks are much better than some I've used in terms of fumes. I've used this set-up for my last few mountain marathons and no way would I go back to gas.
