I'll be coming up from the south traveling along the coast as best I can. I'm aware of how the cascades get and OR in general. The wool was brought up to me in my conversations with people. The mummy bag with a liner is probably the warmest, lightest, and most compressable option. Wool is just nice and a blanket has many uses. If I can find a small but light wool blanket I'll probably take that. I find such a thing unlikely though so I'll probably stick with the big agnes bag. Thank you for the opinions
