Actually Josh Sharpe said on the Coast to Coast Pinball podcast that people have the right to play in the lowest division they are able to and should. I kinda disagree since I feel like I'd wanna play in the highest one I could (at Pinburgh last year I was more a "C" player but if you were on the bubble you could tell the organizers if you wanted to bump up or down and I picked up into B). I get why it is more fun to play down since you have a better chance at the money and glory, but I think I just like being punished
Oh and on the EM thing, they rock - I used to dislike them too and in fact at Pinburgh I did beat the Pinburgh champ (Jim Belsito) on only one game in the group we were in and it was an EM
