Alot of these comments seems to be aimed at the "Koi-Unit". Stephen's personal challenge was certainly aimed at Aquitori. Not that they need defending but I don't think it's accurate to call them armchair anything.
They've supported every show in Northern California that I've heard of and many shows in Southern California. When I say support, it's not just showing up. They do all the other stuff that help make the shows successful - set-up, tear-down, benching, basicaly whatever needs doing.
As far as accomplishments go, if it's about having a good eye and understanding what makes a koi good, then you can show that thru winning baby champ(s). If it's about koi husbandry, then you can show that thru winning mature champ(s). The koi unit folks have done this so that deserves some acknowledgement.
They seem like a bunch of young, enthusiastic hobbyist that have knowledge and energy to share. Why not let them do that?
