I love all the bands you mentioned (except GnR) and I must say...
the Holy Diver is your pickup!
powerful but not overpowering and has a ton of every usable frequency
it's fat (and I mean FAT, not scooped PAF fatness), but extremely balanced and versatile
the lead tones sound very thick and fluid (think Jerry Cantrell soloing live), the cleans are bright and crystal clear and it's surprisingly tight enough for Pantera stuff
the clarity is incredible for that amount of output and mids
definitely my favorite bridge pickup
I recorded this rough video with it

it has a lot more bass than the stock pickups, BUT you won't get that impression cause it has a lot more mids and highs too
you'll get a much fuller sound without sounding "bassy"
but if you're really worried about it, try its brother, the Rebell Yell, for a brighter tone
