I just ordered a 1k spool from http://paracordking.com/ i dont know much about paracord but i am really happy with this stuff (feels much better than that rothco cord). i know its really hard to find the true mil-spec cord and if you can find it, its super expensive. Me and 3 of my cousins strung up some line and hung on it (about 590 #'s combined), it stretched but did not tear! it has 7 inner strands and the sheath feels tough. I'd order from them again.
