I'm kinda partial but the Senior Prarie Classic in Hays is usually pretty tough...Buhler, McPherson, Dodge City, St. Francis, Ellis, Russell, Salina Central, Hays High, Shawnee Heights, Phillipsburg, Wakeeney, Ulysses, Ellsworth, Goodland, Haysville-Campus, TMP-Marian, Hoisington

Not great numbers of teams, but quality teams none-the-less....gets my vote, never attended any of the other ones
