I say keep the 7 Tech rule, but make it so Double-Techs don't count towards it.
And no replay for fouls. Thats stupid. Until you ref, you don't know how hard it is, so some of you need to realize how horribly challenging it is. You could think you are calling a perfect game to find out you didn't. If a ref called every little tap, games would take 67 hours. The aggressive team will always get the calls.
