Im super biased here, but Lindenwood has a much larger program to pull from if you're looking to form a level 6. They have a large coed advanced, small coed advanced, and an intermediate small coed. And they've won NCA in one division or another the past 3 years. STL also has Chrome which has been the most successful international team in Missouri/Kansas.
Plus, UCA teams don't tend to crossover to allstar as much for whatever reason. All the gyms we think of that pull from colleges to build a level 6 international program (Gymtyme, CA, Cali, T&S, Tribe) pull athletes from teams that compete at NCA nationals (Navarro, TVCC, Louisville, OSU, CBU, OCU/OBU).
Besides KU is a good hour from KC unless they were on the Kansas side, which would be right in KC Cheers neck of the woods.
