Have to get a spin halyard for an ARC 21. Any recommendations as to what brand has been best for your use. Diameter is 1/4" / 6mm.
Thanks, Scott
I use dinghy star(not sure if it's the pro or not) because it was low stretch and a shop was selling a whole spool on eBay for nothing. Honestly it works just fine but because of the fine woven dyneema cover it's kinda stiff and if it gets a loop can get caught in blocks. That was an issue only for the blocks at the back of the tramp where I was routing the halyard. The block at tip of the pole hasn't had any problems. I've since just added large rings for the tramp routing and it's been just fine.
I use Alpha Ropes SSR Line in 3/16. It's a single braid so you don't get the twists like you do with a double braid. I also splice it to 1/8 Amsteel to make it run a more free up the mast.

I use Robline racing sheet - dynema blend
soft, doesn't absorb water, doesn't burn up my spin - supposed to be hockle free
