Ok I know there was a post on this a few months ago, but I can't find it, so;

Needing to replace various 8, 10 and perhaps 12mm rope, so which "traditional" looking 3 strand polyester rope does the best job? I'm looking for halyards and lazyjacks, so I don't want too much stretch, but at the same time, they must be very UV stable and cope with long exposure to sunlight.

Hardy Hemp? Roblon? What has stood the test of time? It must be reasonably easy to work yet no horribly expensive.
