I tried the PI CoT Demons farming, but those maps make me not as happy as AE. I don't have that fluid rotation between mobs because they're across a non-linear map, the mobs run away a lot, and the visuals suck when my camera gets stuck around corners. I enjoy the destroyed city maps like drecks' or the carnival map, but it's not as relaxing as an asteroid IMO.
My opinion aside, I could get behind a double inf weekend for non-AE content.
