My _personal_ opinion is that you don't need all of the redundancy. There are a few things I don't think you really need. There are a couple of things I think could be replaced with better alternatives. I'm not sure I can follow the whole thing, but here are a few examples:

base plate compass and magnifying glass - you can get a compass with a magnifying glass built in. (redundancy)

orange trail tape (not needed)

Coghlan's 4-in-1 whistle - (better alternatives). You don't need the little doo-dads on the whistle. You already have the full-size stuff. I'd get a Fox 40 or, if you have an REI near by, get one of their little tube-shaped whistles. They are normally by the key chains.

Utility knife blades - (not needed)

blanket pins and safety pins - (redundant). Choose 1.

nails (not needed)

super glue (not needed)

8 buttons (don't need that many)

paper clips (not needed)

zip ties (not needed)

brass wire (not needed)

flexible saw (redundant) - you already have a folding saw

aluminum foil and garbage bag - (not needed)

hammock - (not needed)

Coghlan's space blanket - (better alternatives). The AMK 2-person blanket is a much better choice. It doesn't sound like you are wrapped in aluminum foil, it has a softer feel to it, it drapes around your body more easily, and it is bigger so you get better coverage.

Light sticks (not needed)

hand warmers (not needed)

fire starting stuff - you have three ways to start a fire, plus a stove and fuel tabs. (redundancy)

First aid kit - overkill. You can get by with a lot less. You need enough to get by, not enough to run the emergency ward at the hospital.

insect repellent and headnet - (redundant)

four knives - (redundant) One good knife is enough. If you really feel like you need two, okay. But I'd definitely get rid of the leatherman and the opinel.

Okay, I'm fading here. I think what I'll do is go get a cup of coffee and come back and just delete the stuff from your original list that I don't think you need an post that.

To be honest, your list looks like a compilation of a bunch of stuff you've seen suggested but which you've never actually carried. I think it will trim itself down naturally when you start using it.

And I have this nagging feeling in the back of my mind that I've come across as a bit of a jerk in various spots in this post. My apologies if I have.
