Re: Best line for jib sheets
I'd go with thicker line for jib sheets. 1/2" or more. The thicker line is much easier on the hands if you're constantly trimming in a race. If you have a self tailing winch, you need to make sure it fits comfortably in the slot.
High tech lines are a good option for halyards as they stretch less. Maybe not quite as important for jib sheets. I use double braid poly for jib sheets and spectra for halyards.
