Ed, do you feel the Gunslinger has enough room to pack out a boned out muley, along with a sleeping bag and other gear? I'm also looking at the Just One, but I wonder if the Gunslinger might be enough for my needs. I need a pack to hold enough gear for a maximum of 2 nights and 3 days of hunting, and have the ability to get a deer out plus my gear all in one trip. I want to hunt with the pack on, so it needs to be quiet and not overly large. I would think that some stuff could be strapped on the outside if necessary. What do you think? Would I be better off with the bigger Just One pack?
