California Youth Symphony vs El Camino Youth Symphony?

My kid is accepted by both California Youth Symphony (Junior level) and El Camino Youth Symphony (Intermediate level) for 2009-2010 class but could not decide which one to go.

Any suggestion? My kid plays violin. 沒有經驗,不知道應該選哪個? 請有經驗的指點一下, 萬分感謝!
