Wow, someone should post an entry form to the special olympics if you're arguing about retarded topics like this one. That said, I play front, I have an IR3 with a drop. Weird, I know, but it lets me suck the gun up closer to me and actually use the gripframe like it was designed to be used. Being a front player is economical, too. Lot's times I'll be out before I can shoot 200 balls!
But yeah, communication with your team is key, you should be either shooting, looking, yelling or running at any given time.
