Does anyone have any experience with Spectra parachute cord? It is supposed to have the same 550 lb. strength as the mil-spec parachute cord, but is more abrasion and cut resistant and is only 2.5 mm in diameter. The outer sheath is polypropylene.

If anyone has any experience with this cord, I'd like to hear from you. Please tell me everything you can about this cord. I'd be very interested in your observations. Among other things, I'd like to know what the core is made of. Is it solid, or is a made up of a number of fibers? Does it hold knots well? Does it, or can it, unravel? Does it melt well? Does it get slippery when wet? Does it tangle easily? Any and all observations would be welcome.
