Scholomance, or a Full strath clear, whichever's easier for you(probably scholo) hands down. Scholo bosses all drop things that DE into large brills fairly reliably, there's alot of bosses and not a whole lot of trash outside of the boss rooms themselves(Just skip Jandice, she's not worth it man); you can get 8-12 per run of either, and Scholo also provides stuff like Darkrunes(which raiders eat up off the AH like candy), while Strath might drop some Righteous Orbs which still sell well to twinks for Crusader
