Call of Duty: Black Ops Zombie Maps?

I have all the zombie maps including the four maps from waw on black ops. I want to play them with my dad but he's not used to any of the maps. I was wondering if someone can tell me which map is the easiest and which map is the hardest. ThanksCall of Duty: Black Ops Zombie Maps?
For WAW i would say the order from EASIEST to HARDEST is Der Riese, Shi No Numa, Nacht Der Untoten, and Verruckt. Der Riese can be easy if you are good at zombies and know how to play. Nacht Der Untoten is easy for beginners and can be fun but there is no perks. In black ops it is Kino Der Toten, Ascension, Call of the Dead, Five, Shangri La. If you want the easiest map of all I would say Kino Der Toten, if you just run a circle on the stage the game can go on forever practically.
ok, Der Riese it the biggest and hardest map of all, Shi No Numa is the 2nd hardest and the easiest map of all is Nacht Der Untoten.

Nacht Der Untoten is the smallest and Der Riese is the biggest.

I think Der Riese is the hardest from what I heard. Its a very big map. Haven't seen the entire map myself.

You might want to start with Natcht der Untoten. It is the smallest WaW zombie map.
kino dead ops ascension and call of dead are easiest five and shangri la are hardestCall of Duty: Black Ops Zombie Maps?

ascension is easy
