This is how the lazy jacks on my last boat were set up. The different colors represent different lines. The red was wire rope, probably 1/8" or 5/32", attached to the spreaders. The green was something like yacht braid, around 5/16" (if memory serves), run through a ring at the end of the wire rope, terminated on the boom at one end, and through a cheek block at the other end, where it could be adjusted and cleated on the boom. The yellow was a third line, also run through a ring, but terminated on the boom at both ends.
The green line was long enough that it could be removed from the horn cleat and just let loose, with a stopper knot at the end, and the whole thing could be pulled flat against the mast and bungied neatly at the mast. Took seconds to secure, and with a black mark on each of the two sides (green lines), all I had to do to reset them before dousing the main was pull out the slack and cleat them at the line (still some slack in the whole system, though).
It was a bear raising the main with the lower battens getting caught until I had that 'doh!' moment and realized why they went to the trouble to use cheek blocks and a cleat, with enough line left over that it had to be coiled when the LJ's were in use (not much, but too much to just leave laying on the deck). Usually, I'd put up the lazy jacks, douse the sail and tie it with just a few sail ties, then when at the dock, pull them back to the mast, neaten it up and add more sail ties, then cover - made it way easier to put the sail cover on without them in the way, even though the sail cover had slots for them, and it was ready to go for the next sail. Leave one or two sail ties on when prepping to hoist so it's not in your face, then just reach up and grab the end of the sail tie and pull it off while hoisting the main. Easy peasy.
