Dyneema all around since I strip the cover exposing the core to UV. NE Ropes Endura Braid 8mm (5/16") for jib and spin halyards and 10mm (3/8") for the main. Samson Warpspeed is similar but a bit more expensive and has a tight cover. I find it difficult to splice especially if you don't strip the cover. But if you are paying a pro do the splicing, I think that tight cover makes it longer lasting. Yale Maxi Braid has a fuzzy cover, good for hand feel and winch holding, but the core seems loose compared to Endura Braid. In my experience Maxi Braid breaks down more quickly if you are strip off the cover.
