No need to change a thing
Jean and Steve & Loren,
The photo is a perfect shot of the classic tri halyard masthead, in which you have a center halyard dedicated for headsails, and 2 "universal",aka "wing" halyards, which are INTENDED as the spinnaker halyards or secondary genoa/staysail/ blooper,etc. halyards.
In a racing scenario, it goes like this: You begin sailing upwind on the center halyard. If you need to change headsails, you use the wing halyard that will make for the easiest change based on whether you are doing a straight line or tack change, or if you anticipate needing one of the wing halyards for the first spinnaker hoist, use the one you don't plan on using for the kite. If you get to the windward mark (or the point where a kite is the sail to use) and have not changed headsails, you can use whichever wing halyard makes sense-usually the halyard which is on the same side the the side you will be setting the kite from. If you have made a headsail change to one of the wing halyards, you will have to use whichever wing hal. is still free. If the free wing hal is on the leeward side (where you will set the kite from), fine. If the only wing halyard free is on the windward (high) side, just bring it around the front of the headstay and connect it to the kite. You will be hoisting it as it rides up and over the chafe cage, but that is why the chafe cage looks like this-it is meant for it.
Anyway, I could get into the whole issue of how to plan which spin halyard to use in different situations, but the point here is that these ARE spinny halyards(and secondary genny halyards at the same time), the masthead cage is appropriate for use in "real" conditions, and there is no need for any other bale or fittings up there to have a workable spinn halyard..
For you guys with furlers (which should always be set from the center halyard), you essentially have a spare universal halyard on each side. You can use either one of these for a spinnaker, heavy air headsail, drifter, or whatever.
So-the center halyard is only for genoas, jibs or staysails-but NOT spinnakers of any sort(because it is under the headstay, you can't very well gybe a spinnaker from this halyard, right? At least not without wrapping it pretty badly around the headstay. This halyard is limited to sails set on centerline that remain below the headstay. The "wing" or "universal" halyards can be used for any of these. Genny, jib, staysail, and all types of kites as well.This set up, when managed by your "bow professional", allows you to to change sails back and forth, upwind or down, and always have one (one wing or centerline) halyard free for the next leg. Very efficient without wasting space, rope, or weight as you would with a 4 halyard set up like in the old days (with 2 genny and 2 spinny halyards)...
Cheers,

Hope this helps, guys!
