S-curve fairway for a slow arm.

I'm looking for a disc that will turn a little bit when thrown flat from 200-250. Something that will fade a bit at the end or fight back to straight if I put it on too much anny.

I used to get a good s-curve out of a beat in star teebird before I lost it. I replaced it with another star teebird that's getting beat in but doesn't want to turn. My f3 gives me pretty much the same shot as the new teebird, and my f5 has almost no fade at all. Both prodigy discs in 500 plastic.

What should I try?
