One suggestion for a little more JIC. Duct Tape: It holds the world together. A little trick I learned in AIT, instead of lugging a whole roll around in your BOB equip, tape a few wraps (maybe a yard or two) around a canteen or a knife sheath, that way you always have some when you might need it. It makes a great emergency sling, as long as you don't mind pulling a few hairs out to get it off, and Gods know what other myriad uses you could come up with for it.
