not that engineering is a democracy. There is actually a right answer to most engineering questions. If you have a halyard lock (no tension on the halyard at all, once locked), the mast sees only the luff tension as a compressive force. With a standard one part halyard, the mast sees twice the luff tension. With a 2 part halyard, the mast sees 3/2 the luff tension, or 25% less than a one part halyard. Some very large yachts have a 3 or even 4 part halyard.

I have a two part halyard on my mainsail, half the effort to raise and tension, twice the line (same amount of work done). I have to coil 130 feet of line, but I do it just as Larry does, figure eight and then stuff it in the line bin. One other disadvantage of the arrangement is that the dead end of the halyard is at the truck, not easy to inspect it for chafe and wear there.
