I have the exact setup that you are asking about
"HH Expedition Asym
JRB Underquilt (could be nest or no sniveller as long as they fit the hammock)
Python skins or homemade skins large enough to skin underquilt w/hammock
MacCat Deluxe or equivalent larger coverage tarp"
I upgraded to the ULBP. The MacCat that I have is not a hex, it just uses two stakes. I don't see this model on Brian's website, but it was called a "standard". It has a "third genereation" style of corner reinforcments and D-ring attachments.
The Nest I bought from a guy named Tripp on Whiteblaze last Spring. It is an older model one of the rare Turquoise ones. Awesome color, but a heavier fabric than what they now use. I used it on one 4-day trip last Spring. Prior to that I had the Nest sent to the Jacks for the Omnitape and Down-To-Earth pad modification. I would include that Down-To-Earth pad too (for go to ground capability), along with Python skins. My Expedition Asym hammock has been used many times, it is in very good condition. With the possible exception of the shoulder pull-out cord which was torn out and needs to be reattached. I would make that repair if you were interested in purchasing the whole package.
I meant to say, I will also include a Supershelter with underpad for that price. That way you can use the Nest as a top quilt.
Asking price $375.
