Yes, It sounds to me like it's already been well thought out. The Paraliminals work well for teenagers. Some have been using them since infancy. For children younger than 12 stay with the simple ones, Memory Optimizer, Self-Esteem Supercharger, Personal Genius, Prosperity.
If your son is already a keen rock climber the Paraliminal boost will be a bonus. (Paul's sons were using them as teenagers.)
I think it may have made him dizzy because he was trying to listen to both voices moving the mind back and forth. Remind him not to try to focus on either voice and if he seems to sleep through it, that's fine.
