I'd have to back Dicks statement as well. Omosako has great name for shiro. But there are others as well.
To take a different spin on it. Omosako breeds nice showa as well too
I think if the fish is nice and you can see its future. Nice fish are nice fish no matter the brand name. I don't think I ever let a nice fish pass me by just because of a name.
When I think of smal Breeder for shiros I think of Marusho. He breeders many good variety and Shiro is one. But then again he make a mean Sake'
Currently I own a Shiro which was acquited at Ogata. I am not sure if Ogata bred it but it didnt stop me from buying her.
