in terms of output that would be the ceramic pig
eq'wise the neck versions of warpig and miracle man used in the bridge have some similarities with the 85
maybe a custom miracle man with alnico 8 would sound good
i was looking for the same thing as you, then i ordered a holy diver and it's favorite pickup ever
boosted and downtuned, my guitar sounded as massive as when it had a 85 in the bridge, but with much more tone and depth
i'm back to the miracle man temporarily, but it's voiced like the 81 (focused and tight), not the 85
