low/ medium output pickups can pull off a good metal tone if you supplement it with a good amp. of course, hotter pickups would do the job better because there's more output on offer but it's not exclusive.
for a good overall combo, i'd say:
neck- Duncan Alnico II Pro
bridge- Duncan JB
if you insist on more bass in the bridge, the Custom is a good, balanced humbucker. it's a humbucker based on the '59 model but given added personality. i'm from the Duncan camp, so this is a Duncan perspective. i've had enough of Dimarzios, despite them being a good brand name...
