Not in Southern California, lol.
Completely understand. Sounds like you guys will be fine.
In my DD's situation, stayed in our age group and chased a Nationals berth through 1st year 14U (and got there every year). This past fall, we jumped to 16U before freshman year and it really paid off for her. But it's really been a combination of playing top-notch competition, in your actual age group or playing up. Good luck
