The cord referenced by the original poster is 2mm Spectra accessory cord, not the 5.5mm Spectra cord often used by climbers (like me) to sling chocks and make tie-offs for oldschool rigid Friends. If you're a climber with much experience, you know what Friends are.

The 2mm Spectra cord referenced above is similar to Kelty's "TripTease" guyline cord, though a bit thicker it appears based on the strength rating. I know the Kelty cord does not have the separate inner strands like nylon 550 cord, and I suspect the 2mm cord doesn't either.
