Well, I just weighed everything up. Total weight of my winter logics kit, including hammock suspension, is 121.8 oz. == 7.612 5 pounds. I don't think that is bad at all. Only items I have not factored in are tarp lines and stakes. I will be carrying different stakes depending on snow and frozen ground conditions.
I'm actually concerned I will be a little too warm on tomorrows trip. The low tomorrow night is currently forecast for 34F degrees.
