Skarner Builds, Skill Orders, Runes/Masteries?

Could use some ideas for building Skarner. Usually I've been using my AD jungler runes and my Tank Jungler masteries with him.

Skill order with him has been Q - W - E - Q - Q - max R>Q>W>E.

Building Cinderhulk on him, then IBG, then I prefer to play him as being tanky and using my ult to make easy picks.

Just started picking him up because Vi/Sej/Voli are always getting picked/banned these days, won three times in a row, rattled by a very crushing loss.

Should I build him as a tanky jg like Sej/Voli, or go more towards being an AD bruiser jg like my main/fav Vi? Could use some suggestions for ranked performance on Skarner, too.
