I moved this summer from a part of the state that used 3 man crews exclusively to a part of the state where nearly everything that isn't a huge school uses the dual system. Last few weeks when they have brought in a 3-man crew I've been amazed at the choices to go three whistles, and when they used flags, how poor the flag mechanics by AR's have been... flags in wrong hand, crossing the body, flags flapping loudly when running the touchline, not mirroring each other on substitutions, etc,...and guys not staying with the next to last defenders. Do most of you work 3-man or dual, and when you use 3-man is it usually 1 whistle and 2 flags or 3 whistles?
