what temps are you hunting in? I personally have ran a 20 degree bag for years. I have used it down to close to zero, I simply just wear more clothes depending on the temps I expect that night. I hate being hot in a sleeping bag, The whole too hot, stick a leg out, too cold thing drives me nuts. in cold weather I also wear a large beenie that pulls down to my nose that keeps my head and neck warm, kuiu marion 210 bottoms, 210 top, hoodie, even 210 gloves to keep my hands warm if I poke them out at night. IMO this is way way better than trying to use a zero degree bag. My dad always bought me zero degree sleeping bags as a kid and I hated them. I run a cabelas boundary waters large rectanglar down bag, plenty of room, they no longer sell them, but LL bean makes one pretty close to it currently. its light enough to backpack and I have taken it lots of times that way. its also NOT a mummy bag either. kinda a unique combo of light weight and good size. had it for nearly 15 years, its nice knowing my sleeping bag and exactly what I need for a given night.
Yikes...
