Personafixes, how do i role played personafix BTL? Options

[Frackula]

Personafixes looked like an interesting BTL, especially in a roleplaying scenario, but how do they work again? It says skillsofts and mnemonic routines. If your BTL personality is, for example, James Bond played by Sean Connery, what's preventing you from picking up all the social and knowledge skills that go into the Bond character? What is this "RAS override" which I must have missed in a previous chapter? My search fu is weak.

And another thing. What if you were to make a personafix based on someone you knew? Or better yet, someone you captured... How effective are they at fooling others, given the right disguise? I'm certain nobody will notice a difference in behavior.

I'm also thinking of making some kind of "remote personafix" thing to enforce a temporary personality on someone else, possibly in spell form instead of wireless.
