Well crumpler you're looking at a couple of different things there. You were originally asking about woodsball, then started talking about a tournament style walk-on site - tournaments came out of the woods many years ago.
Most of the sites in areas like Norfolk are rental customer sites, and the majority of people who come on here have their own kit. So though these places are doing OK with their rental customers you're unlikely to get many of the people who hang out on P8nt wanting to use rental kit or pay rental prices for paint & game fees.
You might get a better response if you more clearly defined what type of ball you want to play. Woodland walk-on? Big/scenario games? Tournament type training? Sup'Air walk-on? Or rental play.
