For most of my UL trips I carry a greasepot cookpot, 4 ounce fuel bottle, .006" aluminum windscreen, one of my Thru Hiker stoves, Firesteel Scout, and a Snowpeak ti spork. The whole kit comes in at about 7.4 ounces.
If I'm going SUL I use one of 2 setups: either 1)a firelite 500 pot, Gram Weenie stove,either a 2 or 4 ounce fuel bottle, firesteel scout, .006" windscreen, snowpeak ti spork (about 6.2 ounce) OR 2)Heiney Keg pot, a new, as yet to be named stove I've been testing, .006" windscreen,firesteel scout, 4 ounce fuel bottle, litemyfire spork (4.9 ounces). I've been leaning toward #2 so far because the new stove will boil 16 ounces in a keg pot in under 9 minutes consistantly, burning out in about 11 flat. Testing continues........
