Hi Jason
For those of you that don't know this link provides access to the auction koi pics and videos.
http://www.momotaro-koi.org/english/index.htm
We do this 'what would you buy' over at KoiChat for every Momotaro Auction.
Amongst the posters there both kohaku 8 and showa 15 received mentions but no-one mentioned sanke 4. There was one particular koi out of the lot which received most comment!
Videos are indeed a cracking medium by which to display koi for sale as you can see so much more of the fish than you can from a pic, you get a much better idea of the volume, the way it swims, the way the patterns wraps around the koi, etc, etc.
