That's my view too. I even bit the bullet and decided to try a site alot complain about, phoenix Airsoft. Not a bad site in its self but wasn't a fan of some people there.
Tac house the Stan in Sheffield isn't a bad site at all, nicely laid out over 3 floors of old factory, some of it I feel is perfect for people who love fast play. The owners are decent and run it well as they did in their old site in chesterfield.
In November I'm travelling to Gloucester to try the prison cqb site there, hopefully from what I've heard it's a good site and ran well. No idea how I managed to convince the Missus that while we are on holiday that way that I can play a game. But she agreed and allowed me to book on, I'm sure she'll enjoy herself with the dogs for the day.
