To answer Mike's question.
Some quilt manufactures are moving towards using vertical down tubes instead of horizontal with the claim that these will conform to body shape better though I am doubtful about this. Sleeping bag manufacturers have been using this style in winter bags for years but mainly for down control. The thinking is that vertical tubes will stop down from shifting downhill, out to the sides of the bag and I can see this would be especially helpful in a quilt where you are rotating within the quilt rather than rolling the whole thing over like in a winter bag. If the down shifts to the sides it would lead to drastic loss of loft right over the top of your body. I suspect adding an oz of overfill also helps limit down migration and may have a lower weight penalty than a complicated baffle system.
I've sort of developed an unconscious roll and tuck that I do almost without waking. We use a quilt at home so I'm familiar with those side sleeper gaps. To pull the quilt around me I tilt from a 90 deg. side lay forward by 30 deg pulling the quilt in behind me, then back to pull the quilt in front of me in to create a snug fitting surround. You have got to have a wide enough quilt to do this though.
One big difference between a custom quilt and an open sleeping bag would likely be the neck drawcord and snap around the back of the neck. Closing the top end of the quilt off really helps keep the warm air in.
I've yet to switch to a full hood, so far I have been happy with a merino toque or balaclava on colder nights.
