Hi David, I switched to spectra for both genoa halyards and the main halyard. They are expensive, they are much nicer on the hands and there is no noticeable stretch. The weight aloft does make a difference....I don't remember the numbers but 10 lbs aloft equals one man on the rail.....or something like that !! Now, bear in mind that I am a recovering racer and have carbon main and headsails. Makes a difference and, after all, isn't your boat as special to you as any AC vessel.
