I would give them 2-3 weeks of OD before moving onto PA for about 2 weeks. PA trains fast, so you might have one of them pop two weeks in a row. After that, I would give them about 4 weeks of JS/1v1 Guards. Since they all have bad JS, this might take a while.
I will also tell you that if their HA gets too high too fast, their salary will begin to spike up a bit. Good luck training them!
