I've talked to Allen before at a DCC about an event at Valley Forge. He was in favor of it. He did suggest that the main criteria for getting into the finals should be average rather than highest run.I think we are definitely on the right track here. There have been some incredible ideas thrown our way and some that we have come up with on our own.
I agree with Kevin that right now the ideal thing to do is to see if Allen Hopkins may have some pearls of wisdom for us on this endeavor perhaps he will have a table or two available to us.
Of course, at the Super Expo there is less time than at DCC, but players are better able to schedule their time.
A lot of good suggestions have been proposed here. If you don't mind, I'll call Allen and see if he is willing to host a 14.1 Challenge and what his requirements would be.
