Jim,
Breeders;whose got it and who doesn't? I know you can't politically answer that but without sampling all breeders...
There are so many variables: turn over, fish load, type of filter(s), to name a few. Some people swear by a certain breeders while others disparage the same one.
When you look in Kokugyo and study the Kohakus:do you think that happens around you (your pond or friends) or are those exceptions? Pg 24, for example, the fish appears to have gained beni as well as quality of red.Pg 28, the first pic shows second hi, and then it's gone. Wow! If only you could count on that.
Tosai, for me, have become harder to pick correctly. Not sure if it's me or the breeders have gotten better and keeping the top stock. Lots to think about.
