While the standard 550 paracord is a favorite among bushcrafters and outdoorsmen, I'm really liking the 275 weight cord. I first bought a couple of spools of the 'tether cord' from CountyComm for use as lanyards but the more I used it the more I like it. What's the big selling point for me? Size. I've only made a half hearted attempt to make cordage and I can't imagine trying to improvise cordage if I needed it, I'd much prefer to carry it. Here's one hundred feet of 550 cord compared to one hundred feet of 275: So you can carry the same amount of cordage in half the space. Is it strong enough? I tried out a bow drill using the 275, two embers out of three tries, no problem. I'm not sure that I'd trust it for a shelter ridge line, but keeping a length of 550 cord for that and exchanging the guy ropes for 275 cord again cuts the size of the line kit in half: I make no claims this is the perfect cordage, but I can't think of a general bushcraft task this stuff wouldn't handle. If you're looking for ways to cut the size and weight of a kit, I think this is a good place to start.
