I'm seriously considering replacing the (once white) 3-strand polyester rigging on my Penobscot 14 with hempex, for a more traditional look and feel. I've got a number of eye splices to make, and at the same time will replace the gromments on my rope-stropped blocks. Making the grommets for the blocks from polyester was not fun, comparing to my "practice" gromment made of manilla, but doable following Brion Toss' instructions. How difficult is hempex to work? I'm also concerned about the longevity of hempex, as I understand it's made of polypropene, which I'm told is not nearly as UV resistant as polyester. I'd like to hear from those who have used it.
