It doesn't have a league tournament, and I'm not sure if it's "a" league or "several" leagues, but the AVCTL has a heck of a lot of good wrestling teams/individuals. From a spectator view, it would be a good tournament year in, year out. Finding the right time and format might be tough for the coaches though.

Division I:
Derby, Goddard, Hutchinson, Maize, Salina Central, and Salina South

Division II:
Arkansas City, Campus, McPherson, Newton, Valley Center, and Winfield

Division III:
