$58/case? Yech. That's not XBall inhibiting, that's paintball inhibiting.
But 100 cases/event seems extreme - there are teams that win DII in PSP with 60 cases, and that's 9 matches in. Reduce the match time/tournament structure. Or maybe even cut back to 5 events - have a season schedule and give each team an off event or something.
I'm certainly not trying to say there arn't obstacles to XBall in Europe, but with some Robbo-induced creativity (step it up or he calls you french, just so I don't have to worry about any action from Missy) you guys should be able to make something happen.
As a sidebar, does anyone have any numberson the number of annual paintball participants in Europe? It's 10 million US-side, curious how hte European market compares.
