Jungling 101

[Jonathan Meer]

I've asked this a billion times, but just so it's all here, for my sake and others

I want to get into jungling after seeing Tryg's hilarious shit (first blooding karma, pwning yi at his blue, lolol). How do I get into this?

As I understand it:

1) Watch Stonewall's videos for information on paths
2) Catch a build (somewhere? Mobafire?)
3) Practice it in a custom a few times to get the path down
4) When in-game, think of jungling as ganking, with brief forays into jungle to farm, rather than farming jungle creeps with brief forays for ganking

And at this point, developing jungle ability is just a matter of playing a shit-ton of games as jungler, ya?

Who should I start with? And please don't say Nunu. Nunu is boring.

EDIT: I'm thinking Amumu, as I love his ganking ability, but I've heard he essentially requires blue, and is very easy to counter-jungle.
