I am not sure Koibito uses this forum very much for this type of breeding discussion - most things are just dumped in the general forum and searched.
I think you have to ask yourself what you want to accomplish in the pairing because breeding koi is a lot of work. You will have to set up at least one temporary grow out tank for the fry of somewhere in the 1000 to 1500 gallon size range. Just growing the fry up to the 40 to 60 day age when you can agressively select will take lots of effort. A reasonable size spawning female in the 24 inch size range will easily produce 100,000+ eggs at 70% fertility with a good single male.
Your female choice is the first priority since you can only spawn 1 and for that choice the most likely candidate is the ginrin hariwake. If she has the size she will be a good choice because a variety of offspring can be produced from the one spawn.
I believe ginrin is single factor dominant based on the fact that we always seem to get some ginrin offspring fron a ginrin parent and this will be a good thing for you. You might be able to expect somewhere in the 25% to 50% ginrin babies.
Hariwake can be a catchall term for fish that are orange/yellow and white. Some are doitsu and some are kin(metallic) as well. A great deal depends on if the fish is colored with white markings or white/platinum with yellow/orange markings. A dorsal marked yellow fish on a platnimu white background would be a great choice to pair with either of your male fish.
Here is a great picture of superior GinRin Hariwake fish bred by Richard Rombold out of San Joaquin:

That fish is the result of pairing a yamabuki ogon with a ginrin Kohaku.
If you pair a fish like that back to a Yamabuki then you can expeck a high percentage of yamabuki and moderate percentage of well marked lemon yellow hariwaki babies.
If you pair a fish like that back to a well marked kohaku then you can expect a high percentage of very well marked patterned offspring of which many will be hariwake and some will be kohaku. You will still be some yamabuki ogon offspring due to the match up of less common secondary genes and modifiers.
In all cases, if you use the ginrin female parent and if she is a good quality ginrin then you should be able to expect some ginrin babies across all color outcomes.
That is at least my best guess.
Good luck!!!
