Posted somewhere around here, or in a YouTube video, there was some lore that with a gathered end hammock the UQ should have more attention. In a Bridge Hammock the TQ is more significant. But in either case, you can’t ignore the other. There are other factors - like the use of a under quilt protector or how low you guy your tent. I try to use quilts that are rated for at least 10 degrees colder than the expected temperature - because by using them outside, I’ve found that gives me the “guaranteed warmth” I want.
