which is the best follower for summoning?

[Martin Robe]

Right, so, which follower would be best for, say, someone who can already summon two dremora lords, but wants MOAR? I figured, hey, now that dawnguard allows you to summon an undead dragon, I want one! But I still want two dremora lords fighting alongside me. So, basically, which follower would be best, or would any work as well if I gave them a staff such as sanguine rose? Also, does the AI in skyrim allow for a follower to not only sumon a creature, but then use a weapon for combat?

Eola summons undead pretty often.

I don't think I have seen NPC summoning Dremora. They just summon Atronach.

You can Dead Thrall a vampire summoner level 40 if you want.
