For years I have used a double length jib sheet.The center of the sheet is pushed through the clew and the two ends pulled through the bight then pulled tight.Doesn't catch on mast hardware when tacking and reduces the weight on the clew in light weather.I leave it on the sail when folding it .Requires re running the sheets for each sail change but it works for me.
Sounds like the KISS Keep it simple principle to me. It is what I have done since day 1 with hank-ons and still do with the rollerfurler. My lines have not worn out yet and I have seperate blocks/tracks for jib vs genoa so I have to re-thread the sheets either way. They are not that expensive anyway.
