How about an easy-to-ventilate, about 16 ounce quilt for above 35*, a 20* bag for 25* to 40* (I'm a cold sleeper), and combine the two for 15*? Below that, I go somewhere warmer due to a lower elevation, which is easy to do in my area.
Yes, I'm a gear junkie and a hoarder so I need some cold, clear, gear logic, outside of my own twisted psychology.
