I have a 10 month old, 64g female ball python (yes, I know she's very small...she was a rescue animal and has been gaining weight since being in my care) who is currently eating F/T fuzzy mice every four days. I'm getting ready to bump her up to hopper mice but I ideally would like to switch her over to F/T rats. What would you suggest I do to make this transition? Here are the options I can think of:

1. Feed F/T mice --> live rats --> F/T rats
2. Feed F/T mice --> F/T rats
3. Feed F/T mice --> live mice --> live rats --> F/T rats
4. Feed F/T mice -->live mice --> F/T rats

I should also mention that she doesn't have much of a coil response. She generally just strikes and holds her mouse down on the substrate and then eats it. She never coils and constricts. That said, should I just try a F/T rat? I want to make this transition easy on her and I worry about adding live food into the equation when I know she doesn't coil around her already dead food. I don't want her to get hurt!
