Warpaint Indoor - I hear they redid it recently so my assessment is N/A.
My brother and I tried out SniperZden to see if we wanted to play there regularly. We usually play outlaw/woods ball, because it's very cheap and we can control our own games.
There were about 12 other guys there and Greg let us all decide what games we wanted to play. He always made sure to ask what we're playing before we entered the field, just so we all knew what we had officially decided. Very laid back and cool. He knows what he's doing and is approachable with any question.
The only field we played at was the speedball field. I dont know how the other fields he has are, but this one was great. Multi-story building, single story buildings, speedball-style barrels, woods in the back. I don't usually care for this style of play, but it was still a blast.
I would suggest SniperZden to anyone who wants to paintball for fun. Keep it up Greg!
