Oh, I should add. Western Iowa still is 2-whistle. I believe that's the standard for the entire state. As for their state tournament, still 2-whistle, although there was talk at one of the rules meetings last year (I only go every other year in Iowa) that they might be considering 3-whistle for state tournament within the next few years. Haven't had a chance to bump into a resident Iowan official to ask if that chatter was still going on this year.
