I'd try the Black Hawks from BKP. Basically a passive Blackout from what I understand.
    From Duncan I like Distortions. From Dimarzio I am personally having good experience with the Crunch Lab, but some of the other guys here seem to really like the Dominion pickup for metal. I'd consider trying that too.

    Some day I really want to try Doug Aldrich pickups from Suhr, but those might be better suited for a more versatile hard rock setup, than a black metal sound. For that kind of thing, I'd also think about some other BKP's. Aftermath, nailbomb, miracle man, etc.
