its just a bit funky of a design that limits you to about 8-8.5" or so in diameter. small pots/pans can fit and sit flat easy enough, but the burner is too big for the little ones any way. anything less than say 4.5" would have flame up the sides. but if you want to use stuff that small maybe a backpack stove should be required anyway hahaIs the problem using bigger pans or smaller pans?
The baja has that rail/handle that would seem to limit you.
The flat has a grate opening that could cause issues with smaller pots.
Both seem to have feet so the can work alone.
the baja has a raised burner support so it should be able to fit about 10-12" pots/pans i think which allows for standard group cookware from home
