By looking at the numbers it appears to me that having sub districts for 16 & under is sort of a waste. Just invite them all to districts which would give them an extra week between the end of high school. Maybe 16U could just be an open invitation state tournament on a seperate weekend to alleviate some of the pressure for mat space at state? 14 & 12 deserve a full circle mat for state and really so does 8 & 10.
