Olaf in the Jungle: What to Build and Rank on Him, and How to Use Him?

So I main in Der Dschungel, and am now fiddling around with other champs for it to find fall-backs. I like and his Norse berserkergang aggression style, even if , or bring more utility (testing these more as well); looking for that feeling of comfort I have with Fat Hands (courtesy of ).

Pretty much, the title says it all. What jungler item and enchant should I use for him? Do I max out Q first for a better ganking tool, W for clearing and dueling, or E for raw damage? Do I build him similar to Vi (1-2 damage items, the rest of them tank-like)?
