Just reading about the complexity of said setup gives me nightmares. Ugh!
You'd likely be FAR better served by going to a 2-line (per reef) reefing setup. With either a block, or low friction ring at each cringle, fore & aft. There are some great web on blocks available for clew reefing cringles, & in terms of the tack, you can use a low friction ring in place of the traditional heavy stainless rings hung on webbing, on either side of the tack cringles.
And if you like, you can use low friction rings, similarly hung through the clew reef cringles as well. Or tying/shackling on a standard block there is an option also (ditto at the tack).
Just make sure to put an extra chafe patch on the sail anywhere which the block or ring may rub up against it. And if you want to be super, pro-active, you can put the block or ring inside of a protective, padded, anti-chafe sleeve/sock.
Also, use bare spectra where the line runs through the blocks, or rings, because it's slipperiness makes things go a Lot more smoothly, & thus needing of less effort on your part.
It's easy to rig short, semi-disposable Spectra pennants for this part of each reefing line. Thus you aren't replacing a whole reefing line, when this section of it begins to get a little ragged around the edges.
And I'd Strongly recommend "painting" the bare Spectra with Maxi-Jacket/Maxi-Jacket II or similar, for enhanced line life.
It's essentially what comes on most quality
lines from the factory, & is what gives them that slick feel, as well as assisting them in not snagging on things. Be it anchor
lines, or high tech running rigging
Just compare Home Depot (or cheaper even) 3-strand line, to say New England
Ropes 3-strand line, & you'll see & feel the difference.
It makes a big difference in a line's lifespan... as touted by, New England
Ropes, amongst others.
ropes calls it Samthane (coating).
If it helps, I get into a bit more of the specifics on how to make the "semi-disposable" reefing pennants, here http://forums.sailinganarchy.com/ind...5106&p=4922277
