Another option is to use a light bag and wear clothing to enhance your insulation needs based on the outside temp. I do this with a 30F down bag and have been able to keep warm in 15F weather.
Two limitation on this:
A). You've got to have a bag with enough inside room so you're not compressing the down when you get inside in with a few layers of clothes. Look at a bag's specs, specifically the inside circumfrence mesure, to find the bigger ones.
B). Don't try this with a bag advertised as 'ultralight"; they tend to be cut extremely narrow (to help limit weight).
Also, if you're going to in a tent overnight with other people, everyone helps to contribute to inteior warmth.
