Once my BB and MacCat(on order) actually arrive and I recover from the new gear smell, I'll PM you about getting together for a hands-on session.
In the meantime, I'm doing some internet homework on underquilts...and finding I don't fully understand the full-length vs. short (e.g. Yeti) differences. Yeah, I know...length/fill/weight is different!! BUT...do the shorter UQ's with some additional leg/foot area padding work as well? I'm thinking Minnesota temps down into the single digits (mmmmmmmm). I'm also thinking about some cheap down comforter DIY makeover into a UQ. Maybe I should recycle my 40 year old Holubar 10 degree down bag into a UQ.
