if put myself in the shoes of someone who recently join the koi circus, I would like see them in this order.
1. tosai selections
2. tosai selections
3. tosai selections
reasons are as follow:
1. based on given 3 choices, I assume that you are target mostly newbies or semi-newbies to koi hobbyists
2. given those 3 choices, newbies would most likely interested in tosai selections since cost of high quality fish such as nisai and older are more costly.
3. experienced koi collectors would more incline to attend any of the given 3 choices.
