Wayne,
If you can, get your hands on the old Koi Bito issues #3 and #4. Great interview with Omosako and focuses on development of their bloodlines. One point that always piqued my interest was the statement of Omosako regarding the motoguro in young fish.
I'll sum up his statement. "I don't care if it is there or not". That is my words buts gets to the point of his interview regarding that aspect.
Personally I would choose C.
Russell,
That is a great point regarding motoguro development that I have not heard before. I sure hope it is pertinent to my 2.5 yo.
OT: I sure do miss waiting for months to get my newest installment of KB.
Sometimes you never know how good things really are.
