choosing tosai Ogon, I will gladly cover but what is being shown as an example is GR and Gin Rin is quite different than standard wagoi. I think most people while attracted to GR still look for the pattern or in this case the color of the prospect when in fact, it's GR that's important as #1 priority.
Body stucture is always the #1 priority in picking year old ogons. Put all you have to choose from in one blue bowl and then look first for the weakest fault of this color variety. When you find koi with under sized pecs they're removed.
Next we look for proper head shapes. many ogons have a head too short or too long "dolphin head". These too are removed. Now we look for a total body length from nose tip to tail end that is 4 and 1/2 heads long. if shorter, they are eliminated. Finally now we get into the color and with yamabuki, it is true you want the lightest one. There are some rare varieties, one bred by hasakawa called creme ogon, that don't fit this criteria but I digress.......
With the platinums or purachinas, you are looking at the hikari or sheen as well.
In GR take the koi outside in the light and then have your eye travel down to the tail. make sure there are no soft or weaker patches of GR, all the same strong presence coming thru the color. if you find soft spots, eliminate this koi from selection.
amazing as you think about all the things I pointed out that go into selection
that something so simple as an Ogon you would have to keep all this in mind.
