The C2's have a more traditional haylard. I plan to switch mine back to a hook and ring like the infusion. I felt that system worked much better and was far easier to keep adequate luff tension.
Change the line that goes through the cleat, and the lazy end of it put on a bungee so it dives into the beam. Most of the time its the crew coming in and out that bumps it and loosens the jib luff.
I used 5mm dinghy control, and tapered it where it ties off at the beam. Yeah, I'm that cool.
