I don't think it's a good idea to close your practices to only kids in your school district. Some of the best clubs open their doors to whoever wants to wrestle. My son is goes to Lansing high school and practices at East Kansas and Bonner springs when the High school season is over. I think you are doing your kids a disservice by not allowing good wrestlers from other schools to work out with your team. It is my opinion that you are only as good as the level of your practice partners, If you have high quality wrestlers in your room everyone will get better.
