You have one intelligent little guy there and this decision is exactly why these forums exist. Trying to provide for our children's need for intellectual stimulation and their delicate emotional systems is quite the task and even if you hit the "right school", you'll be making these decisions over and over again. I find that even though I have chosen to keep my son in public school for now, I'm daily thinking about and often visiting other schools to find better options.
For your son, if you enjoy teaching him and guiding his learning, then homeschooling does not necessarily limit social interaction with age group peers. Is there a homeschooling coop in your area? Joining a coop provides a friendship group and support group for both you and your son.
Does your state allow partial homeschool partial school time? Our state allows you to do that. We can teach math and language arts at home and send him to school for p.e., art, science...etc. Or vice versa.
Just some thoughts....
