[quote=martin_langhoff]Some online shops have fairly good discount rope, even with dyneema core (nautos.com comes to mind). I have found that for halyards, etc it's ok.
But for sheets, specially mainsheet where grip is important, I want the grippiest rope, and grippiest gloves. Modern rigs like the Dart 18 need good leech tension. I currently use Atlas gloves and Samson MLX 8mm and super happy.
It's true, Dyneema lines can be *much* thinner, but they get hard to grip, and can even cut you. A US Olympian lost a finger recently to a dyneema traveler line wrapped around his hand. So I'd go down a bit so that they run smooth through the blocks, but not much.
