Here's my 2 cents (remember batteries are useless after a few days):
So, give me your top 5 items you'd want....
1)Bolo Knife (or a big chopping knife, example:dogfather,battle mistress or machete, something durable)
2)Big Ferro rod

4)32 oz Stainless Steel Bottle

http://www.uscav.com/ProductInfo.aspx?productid=7587If stuck with only 5 items, this is what I would have to say.
1. My goal would be to get out and get rescued as soon as possible and I can make cordage in lue of paricord so what I chose was the compass instead of waisting time for bearings with the stick/watch method or stars the compass; I chose will work anywhere in the world (No sticking due to dip in different zones) and has tritium sites for navigating in total darkness with over a 10 years of glowing. The Epirb is great but is limited to batteries. The Epirb would be better than the compass if you knew someone would get you in 2 days but if it went beyond that I would opt for the compass. The compass will be with me until I became bear food.
Now, if I lived more up north in the cold weather, I would probably ditch the poncho and go with the EPIRB due to the poncho will only buy me minutes if not hours in the cold and I would try to make shelter in the snow by digging a small cave.
2. The big knife allows me to get firewood, make shelter, dig, clear trails, kill and clean small game, polish it for a signal mirror, make fire sticks, cordage etc..
3. Poncho for shelter andfor traveling on the rain, emergency cloths, collect water, and if you get it in bright colors you can use it for signaling and rescue.
4. I chose the 32 oz stainless steel over caring 2 items like a canteen and a cup or nalgine and a cup. ( The rules were set at 5 items and a cup and canteen are 2 items) I can boil water and carry 32 oz of water, use a steripen if I was allowed to carry it, use it for signaling by polishing the bottom, etc.. The 32 oz is a descent size for water, the more water on hand the better.
5.A big ferro rod to start fires because it's waterproof and durable and will last years of strikes. But if giving more space, I would also carry the peanut lighter as well.
I had to sacrifice the light due to the 5 core materials, but with the ferro rod, I would try to get a fire going before dusk but I would try to feel my way to a tree (in theory) and go for trying to find some tinder that is off the ground and make fuzz sticks or shave the inner bark of the tree and try to get fire this way, then go for a torch and look for sap to keep the torch going for a long time. A flash light is only as good as your batteries, that's why I carry a small hand crank one as a back up but it would not be in the core material.
