I would say the best way to convince people to us track wrestling is to just show them how much easier it makes to run a tournament. Track Wrestling pretty much runs the old "behind the scenes" part of the tournament, such as building brackets, updating brackets, etc....

As far as Kansas being mandated by the state to use it. I know the kids division is not mandated. And I am pretty sure the high schools are not either, but after a tournament is ran on track it is highly likely to continue to be ran on track due to the convenience, and the low cost to use it.
