A coaches scratch list wont work in KY currently, there are not enough officials to start with. You allow coaches to scratch, you want have any for the state tournament.
Having asst refs at Quarterfinals is a good start but why start there, halfway through the tournament, if you going to do that, do it from match 1 of the state tournament. However I guess the downside of that is if coaches are not happy with the refs at the tournament now, adding more that they wont be happy with doesnt do much.
Video replay is never a good idea at the High School or below level.
