Unconventional jungler suggestions?
I've been playing League for quite a while. I hit level 30 a long time ago, and have a deep enough champion pool to play ranked, and not just full of 450 IP champions - I learned how to play every champion I own. I feel like I can't buy champions unless I can play them somewhat competently or at least have fun playing them. If I buy them, I feel obligated to level them up to level 5 mastery, and have done so for all but my latest champion, Syndra.
Now, the problem is my champion pool isn't diverse. I own 18 champions, and of them, only 2 are supposed to be played AD, and one of them I mostly play AP anyways. (Before Miss Fortune's E lost 100 base damage at rank 5. Now I don't really play MF at all) All 18 of them are ranged, none of them are real tanks, and, the real problem here, none of them are junglers.
Now, my complete champion pool is 

















I've tried quite a few junglers without success, and I'm waiting on the champion rotation to try more, but for the time being the dilemma I'm seeking advice for is this: Which of these champions make the best junglers and with what builds?
I've found the most success with Lulu, but her clears feel too slow. I seem to always fall behind in levels.

, apparently you can have you plants both dish out damage and tank
the same thing
. He used to be able to jungle VERY well. Now he is an unpopular choice because of his weak early game. If you rune him with what he needs in the jungle you should be able pull it off and be able to help your team around the map anywhere at level 6. I like him because he can basically make two ganks at once or one very powerful gank.
