It's settled then. Bring your back up and a GBB pistol, if you have one. Pistols almost always rule the field there and if everyone has one, a pistol game will be in order. Remember, though, that Tempe requires full face coverage (i.e. mesh lower or a paintball mask). Cloth won't cut it and neophane is far too thin. A flashlight is helpful if they can swing a no light game, but not required. Other than that, it's really come as you are. Whoever is reffing will give you the rundown on the rules, since you're new.
Almost forgot, a barrel sleeve WILL be required for any long arm in the lobby. If you don't have one, they sell them up front for $3 a piece.
