hi gbagua.,
I walked Larapinta solo a couple of years ago. East to west, in a kinda lightweight fashion. 11 days, inc 3 half days. Loved it.
I used a supercat metho stove with a ti windshield and 900ml ti pot. Worked without issue. I also used home made CCF cosy.
I dont know why more bushwalkers dont use renewable fuels.
