Glenn,
That pigtail is for the crew trap line. I like the one the skipper uses. It just comes up through the grommet in the tramp and keeps it clear of the shroud. There is no added block, just route without going to the fairlead at the edge of the hull. I would give this a try before anything else because it is so simple. If you like it, remove the fairlead so you won't sit on it <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />. Its a PITA...literally!
