How can I tell the difference between mil-spec and commercial quality 550 cord? What are the differences? Do I need the mil-spec stuff? Also, where can I find a source for the real stuff, as well as a site which lists the many uses for it. I have heard of the myriad of tasks it can accomplish, but would like some specifics. Thanks for the help! <img src="/images/graemlins/smile.gif" alt="" />
