As a previous coach alot has to do with the money to travel,motels,food, the registration fee for a team (trap most expensive),and the fees to shoot. I can also tell you that the changes that the NSSF have made along the way have greatly hurt some states in regard to the "school team" promotion by Bill Christy. Now the NSSF has actually driven a further wedge between themselves and the ATA to the point that the ATA has renamed their youth program to attract many of the teams that have or will be leaving the SCTP program due to their new rule changes coming in 2009. Mr. Charles might be able to enlighten us better on what some of those changes may be. I have heard that the SCTP State Championships and National Championships in 2009 may not even be registered target events. Most coaches also didn't like having to be "certified" at an expensive course that really didn't help them with their coaching techniques either.
Just my 2 cents worth.
