Should I switch to live?

Ok, so here's some back ground. After I bought Namira, my first ball python, well the first one out of the two I have now. I bought a 10 gallon tank w/screen lid, mini dome, hide, and water bowl from a local guy on craigslist for $20. It was for my brother's baby crested gecko he got at the same time I got Namira. When he brought it to me he told me he had a ball python in it that out grew it and I told him I had a ball python. A week later he called me and asked me if I wanted a female normal ball python w/20 gallon long tank, screen lid, mini dome, hide, and water bowl. First I said no, then I thought about it and made a phone call and arraigned to sell the tank w/screen lid only for $30. So I called him back and got the snake, which I named Nocturnal. Also she had mites something terrible but that is different story which ends with Provent-A-Mite.

SKIP TO THE POINT...

When I got her I asked him what she was eating. He said she was eating medium rats. So asked if she was on live or F/T, which is what I meant the first time. He said she would take either one but he was feeding her live. When I first feed her she took F/T without a problem and I thought I lucked out. Since then I realized she is a picky eater. She will eat F/T but she will eat 1-2 weeks then not eat for 3-4 weeks. I will refreeze rats once, unless they have been sitting out for hours, then I throw them away. After throwing away several medium rats, I switched her to small rats so I could feed them to Namira. I will refreeze them once then feed them to Namira, who has never turned down a meal, the next week. So to the question, should I try switching to live for her? Or, should I keep offering her F/T despite that she only eats it once in awhile?
