it's also used in fishing line. It's what is called a liquid crystal
polymer and is known for low stretch (like Spectra).
I've not used it as rope, but I've used it as a monofilament.
There's lots of synthetics that work well. Your practical concerns are
weather resistance, stretchy-ness (good in climbing ropes, not in
halyards), and failure behavior. Choose what works in your application.
Steel is cheap and doesn't have UV issues.
