Off wind barber hauler self tacking jib sailing

I don’t have any photos but I use a barber hauler routinely off the wind. My set up uses a similar pad eye location as you describe. I leave it pre rigged to the pad eye with a block with the tail going aft to a secondary winch. When I anticipate needing it, I’ll use a snap shackle to attach the new sheet to the jib. As I ease the self tacking sheet, I start to take up on the new sheet until finally the new sheet is taking the full load. The only tricky part is deciding whether to run the new sheet outside or inside the lifelines as it goes to the jib. For deeper wind angles, outside is better. But as you start coming up wind, being inside the lifelines is advantageous. Especially in combination with the self tacking sheet pulling the tack to windward.

Boatman,

I tried a ring but the friction was very very high. The load on the sheet is considerable and a block is the way to go.
