Forget aerating go in with a subsoiler or pan-buster.
I would guess that you know more about this topic than me but does it not depend somewhat on conditions and the horse power available to you.
In early November I aerated six acreas of water meadow using a Ritchie slitter set at 10degrees. This aerated and lifted the soil slightly to aid decompaction.
It did not decompact as much as a subsoiler but was right for the conditions. In any case I have only a 40 HP tractor and so subsoiling would take a very long time..
