Thanks for the tips! As far as my sleeping system goes, your are totally right, the quilt isn't very warm, but paired with my down jacket, toque, gloves, fresh socks, hiking pants, and tarp pitched quite low I am fine getting through nights of -5 at the very limit, I prefer to hover around 0 however. I was not offended in anyway by the BPL staff member asking me why I wanted to go sub 5. I think that's a very important question. I had a look over all of those gear lists you posted and some of them seem like they can be quite helpful. If anyone has specific places where I could easily lose weight at a small cost I would love to hear them. I just can't afford to go cuben, or buy a pack right now. I was also thinking of stuffing some down into my synthetic quilt (keeping the synthetic insulation in too). Would this just be a pointless exercise and waste of down? Any ideas about that would be awesome.
