ermor reanimation in regards to early game expansion

[samoht]

I'm just wondering what kind of reanimation you guys find most useful for early game expansion against indys if/when you use AE Ermor. Souless, ghouls, longdead, longdead horsemen. Granted pretty much all of Ermor's early game units are chaff, and their castle spawns are generally considered superior, but when I'm using bishops and other priests to gather my horde, what i should focus on? or what is best for early game expansion.
