Don't get me wrong, Max is the most brilliant mind I've encountered in many areas, but I wonder what, by your definition, defines "the world's number one mentalist?"
Is it TV exposure, money made annually as a working mentalist (as opposed to a writer, lecturer, or whatever and mentalist), or perhaps reputation among professional mentalists (there really aren't all that many) versus reputation among the general magic community?
Once again, no offense to Mr. Maven, I'd venture most reading this regard him as tops in the field. I just have an aversion to statements of opinion versus objectivity if the qualifying standards are not specified. In addition, I find that I have too much free time today.
In any event, the gathering sounds wonderful and there's no doubt Max will be a highlight for those attending.
