Fearless Fighters is the best place in the St. Louis area for paint balling. It has 10 fields, and all have a different variety (mostly woods oriented). The walk to the fields is not long, and unlike Wacky Warriors, if a field is far away, they drive you to it. They have standard procarbines, but you can upgrade to A5s for $10.
As soon as you arrive, you can obviously tell the place is run by professionals. The refs aren't just high school kids who would rather be chatting with friends on their cell phones. These people are expert players who encourage fair play. They also emphasize safety, which I think is important.
However, there is one putt-off. You can only use your own paint in a mode they call Thunderball, where paint must be brought from home, and the contents of the ball can be modified (ex. Mustard filling, frozen paintball). I brought my own paint the first time, and was slightly angered that i had to waste money on the house paint because frankly, I don't like getting hit by rock-hard balls. But as soon as play started, it all made up for it. The fields are nice and big, and have well-balanced obstacles.
