If he is already going there and likes it and is getting a lot from it AND you knew it was new and rough around the edges to start with I don't see how a new young kids class would be any different than what he is doing already. It sounds like you have already found a good fit and that is a hard thing to do. Honestly I would probably give the new program a try if it were my kid. I don't see being the first class so much as a case of being guinea pigs as a case of not being stuck in a routine curriculum which hopefully will allow a lot of leeway for differing skills and learning styles.
