Doing 8 day GSMNP hike Sept 1. Used SP Gigapower w/ sp 1400 set up for the Nat. Nat Pk last year w/o a hitch. Want to use the wb. So simple and fool proof. Will be doing 20 oz for coffee in am (wife and me), 16 oz on pm for mountain house two person meal. Maybe 8 oz for tea. I can boil 20 oz of h2o w/ 1 oz of HEET in 5:30. Would the weight of alchy out weigh the compressed gas?
