That "cold sleeper" issue is gonna cost you, even if you were a ground dweller. Thank goodness I'm a hot sleeper. I've been getting by with zero degree Hollofil sleeping bag, a blue ccf pad and a space blanket, down to the mid 20s.
The only thing is, the sleeping bag weighs 3.6 lbs. I've tried using a 15 degree sleeping bag (2.6 lbs), but it just doesn't do the job. I always carry the little chemical hand warmer packets just in case; toss those in your sleeping bag and it will warm things up tremendously. It's not a long-term solution, but it's been working for me. I've been thinking about adding a fleece liner to the 15 degree bag, but that's just gonna up the weight, probably back up to 3.6 lbs or more.
You should really experiment in the winter weather where you can really find something that works. That way, the other three seasons will be a breeze. I've spent a lot of nights in the backyard experimenting in colder weather, and if my insulation experiments don't work, I can always go sleep in a warm bed!
