I've got three Eclipses (2 ESPs and an LTD Elite) with Nailbombs in one, Crawlers in another and an EMG 57/66 set in the third one. I've also, at different times, had Mules and Rebel Yells in them as well. The Yebel Yells were great for the styles that you have mentioned but I've now moved them into a basswood superstrat which better suites that particular style. In their place I've now put a Nailbomb (Alnico) set and find that these work very well in a recorded mix (more so than the Yebel Yells that tend to cut through the mix rather than sit in it) but have proved to be very picky with regard to pickup height and string guage (see my other posts for more details). The Crawlers are great in the Eclipse at getting a full, rounded sound and this guitar gets a lot of use as a bit of a work horse, covering a lot of different styles but really excelling in 80's new wave and alternative styles, however of my BKP equipped guitars this would probably be the least "metal" and as great as they are in that guitar, I probably wouldn't recommend the Crawlers for what you want. The Mules were also very good (is there such thing as a bad BKP pickup?), when driven hard they had a good go at hard rock and could nail Steve Stevens' tone from "White Wedding" with ease but again I wouldn't exactly call them "metal" and these made way for the Rebel Yells (which in turn made way for the Nailbombs). If you have anything more specific that you want to know about the EC / Eclipse or the pickups I've used, feel free to ask.
