My suggestion:
* Contact Mitty HS and ask for your son to shadow for a day there.
* Do the same at LG and Saratoga.
* Speak to the HS coaches and parents from all three schools...but speak with the guidance counelors and/or principals too.
Make your decision based on whats important to you. I'm very familiar with the demographics at all 3 schools and that may be yet another factor to consider. Most families in our area would be thrilled to have their son attend any of those schools.
