Agree, now that we are back from our latest OEF tour, I have to switch back to the ACU/A2CU and then convert all of our flight gear back to the ACU pattern. Why not pick one earth tone color and stick with that for the flight gear? The Army Combat Shirt (ACS) is a fun one too, we can only wear it at the aircraft. Pretty easy in my Navy days, pickle suit for both flying and non-flying days, work uniform standing watches. (That got crazy at times, lovis patches Mon-Thurs, Friday was hi-vis/colored shirt day)
