I can tell you that the talk of a new location with full size mats to help out with the speed of the tournament and to help accommodate the athletes in a more suitable fashion (I mean come on it is a state tournament and putting kids no matter what weight class on 1/3rd mats is absurd) is likely going to happen after this year.
The regional discussion is a great one and I am a supporter but it would take much more structure and help from those that want to volunteer to help it be a reality. If that is you and you feel like you can help then contact the IHWCA and let them know you are willing to help out and solve the MS state issues. See if you can attend the planning meetings for the '19 MS state season and actively help to make a difference.
I, as the Kids Director for ISWA, obviously have a vested interest in MS state as we get our MS national team for the Heartland Trip from the state placers so I also support the best way possible of seeding the tournament in hopes that the end result is the best kids finishing the day (or night) at the top of the podium. I would hope that the IHWCA would be willing to listen to people and ideas to possibly improve this process. With this being said that is who and where you need to direct all of the ideas for this to see if change of any kind can be taken into consideration.
