Great thread, thanks for the link. I was about to give up on this pack, but I will now reconsider.
Bear canister - I was looking at the BearVault BV500, but I might actually get the Ursack S29. I have no experience with bear canisters, and very little with ultra light backpacking, and I'm not sure how many days worth of food I can fit in the Ursack (10.5L). Hopefully it will be enough for 9 days.
I use a Tarptent Moment for shelter. If I keep it in the stuff sack it came with, it looks like I might be able to carry it in one of the side pockets, and use the compression strap at the top to secure the other end. Alternatively, I can just take it out of the stuff sack and put it in the rear mesh pocket. It looks big enough for that.
Trekking poles - again, I'm a bit at a loss here. I plan to use adjustable poles, I suppose the side pocket / top compression strap combo could work.
Food - for 9 days, I will probably need around 15-16 lbs of food. Adding water, fuel and the rest of my gear (which is not all ultralight), I will be pushing 32-33 lbs. This seems to be at the upper end of the Gorilla carrying capacity. I was thinking of getting the hip belt / shoulder strap pockets and put some of the heavy / small stuff in there, which will take some of the weight off my back, but still leave me with 30 lbs. Has anyone tried the Gorilla with this weight?
I'm just throwing random ideas around, because I'm new to this, and I need to figure things out on paper before I commit and buy. Buying and returning is not a very good option for me either, I live in Canada, so shipping and customs for each package adds up to quite a lot.
