I think VBL bags have there place but the tighter it fits to the skin the better it will work. But speaking of VBL bags, this one from WM only weighs 4.5 ounces...that is a lot of warmth for that little extra weight:
A VBL bag will definitely work. I do have a couple of problems with it. First, it's a bag. I dislike VBL bags for the same reason I choose a TQ over a sleeping bag.
second, I HATE getting out of those things in the morning (or middle of the night) in the cold while I'm wet. VB clothing at least lets me move around under my TQ, and I can swap for dry clothing "one section" at a time come morning.
