Lack of a UQ shouldn't keep you from winter hanging - you should be able to manage sub-freezing pretty easily and cheaply. I haven't done a lot of winter hanging yet but have done 32*F quite comfortably with a blue foam SPE plug reflective car shade. Did ~22*F with the SPE plus reflectix - back was good though the rest of me was slightly chilled due to pushing the limits of my cheapo synthetic mummy bag. If you are going to use pads do yourself a favor and get a double layer hammock it makes keeping the pads where they beong sooo much easier.
