Now I don't know if I should run both OCs in series, or if I should get rid of the AR OC to free up airflow to the radiator, which may be useful since I'm AT.
What do you think works best?

Personally I'm running a similar setup right now and have left the ar design oil cooler in. Oil temps even when driving 300 km/h are barely above 120 degrees Celsius.
If you see that you get a problem with your coolant temps, I would consider taking out the ar design oil cooler in order to see whether the more unrestricted airflow gives you more cooling.
A friend of mine also has both oil coolers on his car (E92Fan) without problems (even as an AT).
