I think it would be best that no matter how many teams sign up you have the event and adjust the prize money accordingly. If only 7 to 10 teams show up "Play Ball". I would gladly take the reduced prize money. Look at some of the other 5 man series in the southeast, some may pay back entry and some soft goods or paint. Heck most of us play for glory and bragging rights anyway so lets "Get it on"
