"your illusion of making choices is irrelevant - your final disposition has always been known - and he made it that way."
I think this is where the trouble is. Just because God knows the outcome doesn't mean he made it that way. For example, if you've known a friend for an extremely long time, and he has never chosen A over B, you can be reasonably sure he'll pick A. That doesn't he has no choice. God is just someone who has infinite knowledge of you. He knows what you will end up doing, but you still have to carry it out and make the choice yourself. It really just depends on how you define "free will" and "choice".
