How about the "you should make your own gear" lecture?
I'm playing with a standard sized bag right now that I'm converting into a UQ. The most length I can get is 70" which is what I'm gonna call 3/4 length. I like the idea of having my torso covered and dealing with the feet/legs by using some form of support, like a pack that I'm carrying anyhow. Should save quite a few ounces and could be done with down too; I'm just not that talented..........yet.
