I've had the Holy Diver, Crawler, Black Dog and Abraxas bridge models and the Abraxas is my fave of the bunch.
Something about the Holy Diver's mids and bass always ends up grating on me; I've owned 3 and always end up selling them off.
The Crawler just doesn't give me the attack that I need.
The Black Dog is nice, but can become too much for me sometimes with it's very prominent mids; much like the Painkiller if you know what I mean (but much lower output and also far less percussive).
The Abraxas bridge is just right.
It's thick and juicy, but also very punchy.
And it's got nice mids; not overbearing like the Black Dog or Holydiver, but still enough that the pickup has a mean growl to it.
Very under-rated pickup.
The Emerald neck should suit your needs.
I find it a bit too thin for my taste as I prefer fatter and hotter neck pickups like the Aftermath and Painkiller neck models.
But I still kept the Emerald neck in my G&L Legacy USA as it's a nice change for me every so often.
