Hi Scott
Monofilament rope (versus multifilament) is when the tiniest element or fibre in a thread is endless. This happens when it is extruded and then spun together with other elements. The resulting line and rope look quite shiny or ’silky’. Remember, each natural silk thread is also ‘extruded’ from the silk worm, so are just about monofilament.
You can have monofilament ropes, 3-strand or braided from any materiel, nylon, polyester or polypropylene, etc..
Multifilament threads are spun from shorter fibres, for instance wool, hemp or chopped up nylon-polyester-or-whatever.
Multifilament ropes, for instance on the outer layer of braided lines give better friction to the hand, so many prefer them. I on the other hand prefer halyards and sheets from monofilament (braided) rope because it stands up better to abrasion, so lasts longer. I compensate by using gloves, or my ‘Halyard Hauler’.
The fact that the rope is a bit slippery and resistant against chafe was my reason for trying it on my soft euphroe (polyester).
Good luck!

PS: I guess nylon should work. Mine was made of 8mm line, I think it was, but 10mm should also be fine.
