My thoughts on some of these things:

-Leatherman Juice S2 Multitool--no need. What's it going to fix? Take a sewing kit. It weighs less and fixes more things.

-REI Trail Stool--take a small square of foam and sit on rocks and trees.

-Coghlan's Featherweight Mirror--If necessary, look at yourself in your sunglasses.

-Fenix PD32 Flashlight--overkill. Just take a second mini light if you want two.

-Swiss Army Cadet Alox Knife--AND the multi tool???

-Motorola Talkabout MD200R 2-Way Radio - 2 Pack--no need. Just talk to people who are close to you, and stay close the the people you are with.

-Therm-a-Rest BaseCamp Sleeping Pad--we only take on pad--a NeoAir, and save a lot of weight.

-Nalgene Wide-Mouth Loop-Top Round Bottle - 32 fl. oz
-Nalgene Wide-Mouth Cantene - 96 fl. oz.--Soda bottles are lighter and better in almost every "weigh."

-Sea to Summit Folding Bucket - 10 Liters--no need. Just use a couple of soda bottles.
