Gideon, sounds like you'll be prepared for the cold!
I've been testing a few things in my basement in preparation for the next hang. I got my new (bought from hairbear) Cuben tarp all lined out the way I want it with Dutch tarp flyz for the suspension, spectra cord and micro locs for the guy lines, and a cuben stuff sack. This is 18oz lighter than my HH tarp. I'm also experimenting with a wool over cover (just a surplus wool blanket pinned to over the top of my WBBB at this point).
I hope to score some down booties and a down jacket for Christmas too.
I'm looking forward to this hang!
