Hey freelance, why havenít we heard back from you?
Another idea: I thought penney would chime in on this one as I remember some advise she gave long ago.
In the end (under normal conditions), there is nothing warmer than each in his/her own bag.

I found this to be the case because thereís more air to warm up in these larger bags. My wife and I are warmer in separate bags. But we save ~1lb using 1 Megalight and a 9oz homemade sweetie pie. Moreover we give up some warmth; I estimate about 5F lost. So thereís a trade off as usuall in TLB land. To me, the tradeoff is worth it <img src="/forums/images/graemlins/smile.gif" alt="" />.
