If you have a Dren, you should buy these
What if you go on the hunt of a lifetime and your string or cable breaks? Then you will say to yourself, "Self, you should have bought those strings and cables on AT for only $10. Now all of my friends will make fun of me because all I got to do on this trip was be the camp whench! Plus they made me wear that little apron and giggle every time they pinched me!" Who in the world wants that to happen to them? Not you, Mr. Drenalin owner, not you.
