TIZ - I do not know your entire story, but please remember that gifted kids will always be at the top of the class, no matter how drastically you accelerate them (generalization).
LOL - this wasn't true for us, at least for the first 2 years. But I still applaud you for trying the 2 year jump. As you say, the only thing he gets out of school is academics, it really helps to put him where he is happy. I think that a happy kid is easier to get along with, for parents, for teachers and for classmates.
How long did those trial classes last? a single class? the whole year? I would do it anyway, but if the trials were over a month or two, then I wouldn't even worry a bit.
We'll be here for the bumps!
