Great TR Stephen
You mentioned the lack of compression on the Gorilla. Check out Will Rietveldts' blog he changed the shock cords to non-stretchy cords with line locks so they are more like compression straps, looks like a better system to me.
I don't have a tent (tarp) so my pack is always in my "vesibule" no problems yet but I try to keep food odor off my pack. Not just for bears but I don't want a marmot to chew into it either.
I don't know if I'd go with less then 1.4 pounds of food just yet. I've had some similar experiences where I ate minimal food but I always noticed myself eating a lot more when I got home. On longer trips 1.4 pounds a day is very minimal. If you're planning a strenuous trip I'd keep the 1.4 pounds, or at least pack a bit more for towards the end.
