You're right Mark, but I think I'm not complete in my answer, I meant to say Yamato is from the Sakura/Rose bloodline and that is surely a good bloodline..My dealer told me that he has seen a lot of beautiful nisai offspring of Yamato in Japan...but you'r right thats not saying a lot of their devolleping in the future...thats still a question..
But it is always a gamble to buy a nisai in that price range...but if you know things in advance, you loose the exciting bit of the koi hobby...
Erns good luck with your picking..
