LF>Tanky Jungler

I'm looking for a strong, tanky jungler that isn't likely to be banned in draft/ranked games. So far I only use Malphite to jungle, so I'm looking to expand my lineup.

Any suggestions and your reasoning behind it?


p.s. I'd like to avoid Amumu for now.

Cho'Gath: Technically better off top, but has strong ganks, great sustain, and is compatible with the popular duo GP10 item route.

Darius: Solid ganks, great base stats, decent clear time after the first, requires no items to do high damage until late midgame.

Lee Sin: The all-in-1 jungler care package, as long as you can bring dem skillz with ward hopping and landing your Q. Only downside is the lack of scaling into lategame.

Shyvana: Weak ganks, but one of the fastest clear times, good 1v1, strong teamfight presence, and counterjungling ability.

Udyr: Pretty much the above, except with actual hard CC and less strength in teamfights.
