I think with such short notice for this year you should probably just let anybody and everybody show up. A few questions you might consider would be: How many players are you expecting? Will out of state players limit your capability to run both events in a timely fashion? How many tables are at your disposal? For a first time event, although I have no experience with organizing such foosball events, you need to consider a number of variables before making your choice. Instead of having a DYP/BYP, maybe you should split an event with one based on skill level (for newer players to promote foosball growth in oregon), and then an OPEN DYP, that would allow any out of staters as well. Who knows, I might be out of my league, but if I had the tables and capacity I would try to run a "larger" tournament just to see what interest could be sparked as a middle point between chicago and st. louis.
