So last weekend my fiance and I had our two Blackbirds hung from two parallel trees, with a single Mamajamba tarp over us. We were both using down sleeping bags and exped downmats. All in all, I love the downmats - lots of insulation, have that versatility if we need to go to ground, and they pack reasonably small.
That said, we were a bit chilly - I believe mostly due to lack of wind protection from the tarp, although also potentially due to coming off the downmats.
Due to that, I'm considering a couple new purchases... one being a set of underquilts for both of us. I refuse to even consider anything that's not differentially cut, as I already do enough fiddling with setup, and do NOT want to fiddle with underquilt suspension. I want to yank that sucker tight and go to sleep.
That pretty much leaves me considering the WB Yeti, JRB Mt. Washington, and the Speer Snugfit. The snugfit and mt wash both obviously have awesome coverage, but they pack HUGE. These things would easily take up twice as much pack space as even my downmat 7 deluxe. I'm not a big fan of sacrificing that amount of volume. So, I'm at least leaning towards the Yeti - BUT I've never seen a picture of it in a stuffsack. How does the stuffed size of the Yeti compare with the full size diff cut UQs?
The second thing I'm considering purchasing is a big tarp that could be used by one of us as a full winter enclosure (most likely my fiance, as she's a colder sleeper than me), or both of us when we find trees that let us hang side by side like we did this weekend. Since we want to be able use it for the two of us, I guess that makes the Superfly less suited, and a huge square-ish tarp a better choice. Our options there seem to be a Speer Winter Tarp, JRB 11x10, or 10x12 from OES. The OES tarps seem to be a bit heavier than similar sized tarps from others, which is a bit curious, but I could live with that if there's a good reason to go with them. Here I have a bit harder time forming any kind of preference, so I'd appreciate comparisons.
Overall, a lot to think about, but I've been mulling it over for a while, and decided to throw it out here for discussion.
