Thanks for the helpful information koaloha05. It doesn't sound like I'll need to do anything special then, just the usual Nest adjustments. Am looking forward to giving my Blackbird a try this weekend. This really looks to be a significant enhancement over my HH Hyperlite, with no weight penalty. I also really like how well the included BB bag works. One step closer to hammocking nirvana.

The Mt Washington requires minimum tweaking for a nice warm fit. I just pull the suspension and ends relatively snug and enjoy the night. Excessive tightness might reduce the quilts ability to wrap around you shoulders. Haven't tried to really set up the quilt with excessive tension. With the differential cut you would really have to try hard to flatten the loft. Unnecessary tension on the quilt stitching might become more of an issue before loft compression.
The Nest requires you check on the tension. Similar to its use on any other hammock. Too loose mean air gaps between hammock and quilt. Too tight means compression of the quilt loft.
Don't use the side HH position tie outs. Sometimes I need to reposition the lateral lay of the quilt. Usually it has been my left shoulder/deltoid area that is exposed. A 10-15cm "re-centering". Easy to do while laying in the Blackbird. Just unzip the netting and reach down pull on the quilt.
I'm a small person (164cm/57kg). The quilts have more than adequate coverage.
Side note: The HH SS ocf + space blanket using the WS2 in place of the HH undercover works on the Blackbird.
