I am planning a hunt for 2013 in southern co. I'm working out already and need to get my pack so I can workout with it on. 8 to 10 days max without a break. I am looking at the Kifaru long hunter legacy and the sawtooth tent with a medium stove. I have not read anything bad about Kifaru. I am looking at the Big Agnes bags as I am a big guy and they seem to be cut large. With the stove in mind what temp bag should I look at? Am I on the right track? Mid October at 8000 to 9000 foot in southern Colorado.
