Do you mean that Hetfield is using a 60 in the bridge now Wes? Cause I know originally when he started using EMG's it was 81/60, then I noticed some of his guitars had 81/81... what are you meaning he has now?
Anyway, I would definitely just stick with the 81 in the bridge like Wes suggested Curtis. For metal it kicks serious ass... coming from a guitar I have here with middle of the range pickups in it, pinch harmonics are ridiculously easy all over the fretboard... I mean, I was fine with them before on my other guitars, but EMG's just make it easier Its also tight and punishing under high gain.
If you want to experiment, try the 60 in the neck. Its still smooth enough to handle lead work, but you might be able to do something cool with the extra bite, who knows? I really did love the clean sound from it. Otherwise, once you have them installed its a peice of cake to switch them out, so regardless of which one you choose, you can always get the other and just swap it out.
