Couple of months ago, started using a wide-mouth 32 oz. Nalgene bottle/SnowPeak Titanium 700 ml combination. Bottle nests in cup/pot. Minus water, it's light (I leave removable lid behind). Admitted, the pot/cup is on the large side (a plus if you want a reasonably-sized cooking vessel) (the pics aren't to scale with one another), but adds little bulk/weight to the already-carried Lexan bottle. Fits well in mesh side-pockets of fanny pack and daypack. No stove, like yours, but I personally like having stove separately packed so bottle/cup carries a little more comfortably.
