Carl,
I'll ask you the question, "Name one criteria in selecting Tosai that is not or cannot be the same criteria in other ages of Koi."...except with better chances for favorable results in older koi.

If you can name one, its beyond what I can think of tonight. Thus, why single out and use "selecting tosai" instead of selecting "koi" (based on developement) without any misleading innuendo that "selecting tosai" can imply?
Com'on Carl, take a little sip.
Steve
