I have run into your concerns of redundancey before with my own Survival kits. So I have changed my way of thinking when it comes to gearing up. I like to Hunt, I like to Hike, and I like to camp, but NO ONE Kit is just right for all three (for me anyway) Now I have a couple drawers full of "survival gear" out in my shed. I have a Go-lite Rush that I hike & scout with that has it's own small amount of gear in, and a hunting bag that has it's own amount of base gear. Then I add or subtract gear as needed to tailor my pack for what I am doing.
I started feeling really stupid carrying around 4-5 pound of gear to go scouting less than a mile from my house. It just doesn't make sense. But other times I may be camping 2-3 miles from Anything, and want more capability in my set up. The other point is, if you are trying to go light, you don't want to carry 3 knives, 5 different ways to make a freaking fire, 4 compasses, etc, (lol ) Thats what I do, just a though.
