As for the question of personality vs. GTness that you're asking, M&M...
I think kimck is right that it comes down to a gut check. If you doubt that he'll ever fit into school--and boy, do I hear you there!--then I'd say trust your gut....at least for the near future. Things can change, especially as they hit puberty, discover girls, and hit high school where there are usually more and better options for advanced study, so check back regularly.
But I know we've pretty much written off anything but homeschool until at least age 12-14 for exactly the reasons you're describing.
<shrug> It's the right choice for us. Wouldn't be the right choice for everyone. I REALLY wish we had a viable bricks-and-mortar school option instead. I envy those who have a good school fit and still mourn the school life I thought DS7 would have and will never have.
But this will work.
