Thanks for the suggestions.
1) I'll have to see once the new pack comes in, but I've seen on other boards that I could probably strip a decent amount of weight off of that particular model.
2) That's what I've been using, two 16-oz Gatorade bottles.
3) Haven't tried them yet, but I definitely will. The pills are part of my emergency stuff, luckily it has been about a year since I last broke a Steripen on the trail and had to use them.
4) Usually don't need one with the conditions down here. On a chilly night I pack in some lightweight thermals to wear under my clothes.
5) Knives are one thing I always carry two of. A fixed-blade on my belt and a Leatherman multitool in my pack. I've broken several lightweight knives, so I tend to stick with a heavier, full-tang model.
6) Yeah, this is one I found over time. With freeze-dried/dehydrated food, I usually consume about 3/4 pound (dry weight) a day (breakfast, dinner, and stuff like jerky/trail mix to snack on during the day). For the esbit tabs, I usually only need 4, but I always carry one or two extra just in case.
7) I could definitely cut this down. Usually I've just tossed the bottles in my pack, but I could portion them out into smaller containers and cut a couple ounces.
8) Deodorant is mostly for me, eventually I get tired of smelling myself. Mandatory if the SO is on the trip. Smelling like a dead animal marinating in a burlap sack cuts down on certain evening activities :)
9) Yeah, I use a few small ones to hang stuff with (around the camp, off my pack, etc).
