Personally I've found that common quarter-inch triple-strand nylon, safe working load 182 pounds (ABYC), can do most of what paracord does and does some things better. You can pull the core strands out of 550 but triple-strand can be entirely unlaid, all the way down to thread.
Where do you get the cord? Kevin's not the only knot-head in here and I can burn through paracord at an alarming (expensive) rate. I've been using this stuff because it's so cheap, but it's too stiff for a decent knot.
