I'm looking to expand my repetoire of junglers, but don't know who the best AP junglers are. I'm thinking I'll probably pick up 
since I prefer tanky junglers, but are there other good AP junglers right now? (
isn't my cup of tea)
(yes,Ive jungle karthused.....once
nida is the only good ap jungle now
Cinderhulk type. Great at ganking squishies. He can slingshot himself long distances into lane to gank. Does pretty good magic damage for a tank.
Assassin/siege jungler. Pretty notorious right about now. Slightly overrated IMO (not saying she is bad)
Great clear. Good speed/sustain with attackspeed marks and or quints and E start. His ult's bonus hp probably synergizes well with cinderhulk. Grab chilling smite to make ganks easier. Gank by chilling smite + W silence then Q knockup.
Amumu is pretty good. Diana is playable. Elise is really not bad IMO. But the 3 above are probably the best for AP damage (excluding fiddle as you asked)
, and a lot of those are tank AP.
can work too, though I think they are shifting some of his power around here soon (from w active on hit to some higher AP scalings)
