So I have heard it is risky to feed Ball Pythons ASF's due to the fact that after having one of those, they may turn their noses up at regular rats. How true is this?

All my snakes are regular rat eaters...but I bought a breeding trio of ASF's a few months ago and needless to say I have quite a few now. Would like to feed a few out, but definitely don't want to have to feed ASF's on a regular basis. Have any of you had your rat eaters refuse normal rats after just 1 or 2 feedings on ASF's?
