No idea why they did that, always a crowd favorate. Shiro Utsuris usually compete for GC, and Ginrin "A" even though they are not Gosanke. GC and Ginrin "B" for not big 3+1. Depends on the club. I think at Koi America Shiro Utsuris was in "B" for GC, but in Ginrin "A", so a club can split them also. Last year a huge Kigoi won GC "B" at Charlotte. Its a good way to reward a hobbiest for transporting such a huge fish. This year it would have came down to a 33" Asagi or a ~30" or so Kumonryu. It would have been a good reward to one of those.
