I've played against some guys with the UTGs and they're actually fairly decent guns. Like you said, for indoor and small outdoor games it should do fine. Just don't expect the moon out of it and you should be alright. Glad to see someone responsible and intelligent getting into the game. Good luck man, it sucks you in quick.
