Thanks. I find other people's gear post-mortems very useful.
How many days/nights of food did you bring?
That loop inspired me to get a portage pack, a GG Trad #4, and I've been pretty happy with it. Single carry is doable on a decent trail.
The backpacker dogma is ounces make pounds and pounds make pain, but boy that overpriced ultralight crap sure breaks easily. I did go to a light quilt for summer, vs a 3.5 season synthetic fill bag, and that saved a cool 3 lbs. Lightweight paddles are even nicer on the water than on the portage.
The one area I still don't feel like I have nailed down is footwear. On a paddle/portage/wade/track/line/pole/hike/camp trip I want 3-5 pairs of shoes/boots, and that's obviously not going to work packing light. I've mostly settled on trail runners, but wading in the basketball sized rocks I'd rather have something ankle high.
