BTW, in my goal to be UL and hike simply, being a well experienced LD hiker, with a sometimes willingness to shell out BIG bucks for what I considered the HIGHEST QUALITY gear, also having a VERY patient and observational non complaining mindset, after MUCH careful analysis and mediation, I rarely choose to hammock or quilt in winter(20* and below) on LD outings.

As one who regularly pushes himself seeking to expand his emotional, mental, physical, and spiritual self sleep is simply too valuable of an asset to stubbornly refuse to admit when a piece of gear or a system isn't appropriate FOR ME. You have to KNOW THYSELF IMO to do this though. You have to be willing to be honest. And, you should have a very good working knowledge of and in the outdoors to RIGHTLY decide what is appropriate for you or for given situations.
