Meh!
For a boat that is higher performance, I would get rid of the wire to rope halyard, and replace it with Dyneema.
My GP14 is a wire to rope halyard, with a bracket to catch a swage on the wire. When I finally get around to restoring it, I'll replace that bracket with an alloy clam cleat, and a Dyneema core halyard with a plastic button at the top. The button loops through the headboard, lessening weight compared to a metal halyard shackle. Anyway, I'll probably get something with polyester cover, and strip the cover so that the poly cover holds in the clam cleat, but the bare Dyneema core goes up the mast. Again, less weight. It is a racing class boat, after all...
The old wire to rope stuff was predicated on the low stretch of the wire, with the rope to provide something nice for the hands. Nowadays, Dyneema stretches less than the wire.
