Goshiki,
Not the first bit of jealousy. I expect the Epher to throw alot of money at the memphis show so it will be the "Show of Shows". And one worth attending.
If you read anything into my post concerning St Ephen it is that of contempt. I know the Saint all to well. While his money does make up for his lack of character to many, it does not for me. Until he behaves as he should and admits to abuses many know nothing about I will not value his existence.
He is the antithesis of what he told many of us he would be when he put up the money to start his website. And one day I hope he will become what he wanted to be. His money has benefitted the hobby...in some regards.
As to your koi pond endeavor. I have a long thread on themudpond.com (Pond Construction then Lakeluke)concerning a similar sized pond I built (am building). the thread might give you additional insight into what you will want to do.
And I am still hoping to interest a pump designer/manufacturer into developing a Mixed-flow fractional HP pump that the Hobby needs.
The Big Twig might be someone worth talking to over in your area concerning your pond's construction...
now let's get back to "What's the most prestigious Show"
