So, I want an UQ. Tried a HHSS and it just isn't working for me.

I'm also starting to count ounces a bit more in an effort to force my packweight down a bit.

I've been going back and forth between the lower weight of a 3/4 40* with possibly some extra down and if possible some cuben fabric or a full size.

The thinking: I want to be comfortable. After trying to dink around with the Super Shelter for about 5 hangs in pretty cold weather I'm not convinced. I don't want to invest serious money on a smaller quilt and then immediately regret that my head or feet or other part is cold.

Can any of you folks help out with some advice? Is a full size 40* with some cuben (if that's possible) and overfill going to keep me warm possibly in the 30's?

Thanks ahead of time
