I’ve got an eye on the mast on one side just below the gooseneck, with a length of 6mm going through the cringle, and back down to a camcleat on the other side of the mast. Gives a 2:1 purchase to haul it down/forward, and when not in use or when hauled tight, the coiled line is secured under a loop of shockcord around the mast, and the camcleat serves a secondary purpose of securing the main halyard when not in use.
Not a great photo, but hopefully gives you the idea!
