the biggest problem is clearing the hatch ... before you drill for a fair lead ... we have worked with a small block at the pole foredeck anchor which then went to a small block on a slide on the inner jib track back to a harken 150. I'd vote for the mirror image of the pole downhaul line.
Coming into a mooring I like to have as little in the way of bringing in the pickup as possible ... so line led straight back and then a turn to clear the hatch so we can launch spin without it over the edge of the hatch.
