Running backs -- continuous line or two part?

[Brian Duff]

Other way around - HM line from mast aloft down through winch under load, with COVER ONLY tail long enough to allow retracting - the core is the HM line, the cover is just polyester.

Do single part, unless the boat actually needs purchase or spreading of load on deck dicates adding purchase, then use a straight runner from the mast through a block to the windward genoa winch. simple and effective.
