back to the mandarin though-if you're getting an ora from la, i'd be pretty positive its an ora and was on prep at one point in time, with many of those going off prep for a period of time anyhow the pods
is a good sign. the simple fact that they have been raised on prep should make an easier transition to get them back to prep.
basically what i'm saying is... as long as you have a good pod population and are certain its an ora i would worry less about it. If you were going with a less reputable site i would advise against.
