Awww; I just bought a pop can stove Soulsurvivor! Got a stove "kit" from Tin Man; I really like it but had to learn to use it correctly; only works well when you put the pot right on top of the stove. Love how lightweight it is. I'd also bought an MSR Pocket Rocket after seeing CB4's. If I'm going to cook in the pot and want to simmer food the MSR is the ticket but if I'm only going to heat water then the pop can alchohol stove is a LOT lighter set up.
I'm looking forward to seeing the ones you make; how well they work etc.
As for the cold, I'm hoping it is! My Hammock Gear 0 degree full length UQ shipped the other day so I'll have that and my HG 0 degree top quilt should be here by then as well so I'll be toasty warm! My son will use my Phoenix 20 degree 3/4 with a small pad for the feet along with my Marmot down bag used as a TQ. With the right layering of cloths that set up is good down to 25-30.
Just wish there was a stream on the top of Bell Mountain so we only had to carry enough water for the hike up!
