Not really, actually.

I'm basing my belief on the concepts of causal determinism and true randomness - it seems clear that one of these must exist (they are mutually exclusive), and if either exist, free will cannot.

In order for free will to exist, you need to be able to make non-random, non-predictable decisions. This is contradictory by nature, so unless you postulate some non-physical body to provide free will, you have little grounds to stand on. Plus, if you argue for a soul of some sort, this soul would have to break the laws of physics in order to release the body from the limitations of causal determinism.
