dude, if you can get 10 players (which is relaly not that hard) it will cost you very little more than a training day!
Entry (for 10 players) works out at about £25 a head! Seriously dude, you have to try XBall Lite @ D7s, its the best format ive ever played. Also I've seen the way you guys play, and your style of play would work well for XBall stylee formats - dooo it rob! If you need a couple of players there may be some spare on my team - give me a shout
