This is the right age to move from TSC. They are good for younger ages, but if you want to continue to develop, you need to move. AFC used to be the logical choice, but RW hated them and tried to steer folks away. He even talked some into going to Cobb, which makes absolutely no sense for someone from HC. GSA is closer than Cobb and is probably better, but not better than either AFC or CFS. CFS is better for the long term since they are part of the larger CF and have more opportunities as players get older.
