Best 55 Farming Location

I've been farming trolls outside of Drok's, and avging around 700ish per rune with selling items to merchants, and I've gotten a max fellblade, two max dragon swords, and some other good stuff. But.. What's the best location for farming with 55 monks that will offer the most profit, other than UW?

The north exit of Augury is still not nerfed, and offers lots of hydras. As you say, the cave north of Drok's provides a lot of fast troll kills, chest keys and some surprises.
