Out of Nailbomb & Warpig, I think Nailbomb would be better for that music & those tones, however I have another suggestion: Holy diver
It sounds wonderful in alder-bodied guitars, much thicker & warmer than nailbomb, about the same output, harmonics really jump out of it, great metal rhythm "chunk" but huge "weight" on single note riffs, effortless harmonic feedback on long sustaining lead notes, wonderful bridge clean sound, very versatile etc, etc...
That track doesn't give a great idea of what you want from the neck, but assuming you want a pair of singles that balance with the bridge on the clean channel & perhaps offer a useable neck lead option, Trilogies are probably your best bet.
Slowhands give the best Clapton tone (duh :)) - or at least what I understand by the term, however (& I'm speaking from experience here), they don't balance particularly well with an HD & I imagine they'd get massacred by a WP. They'd be an odd match with NB because they're so rounded & soulful yet the NB is a bit of a chainsaw :twisted:
I'd avoid Irish Tours, even though they balance great with NB & HD - they're very bright with a real "pop" & "snap" to them which may not be what you want.
Trilogies are the best bet because they have plenty of power to balance, not excessively bright but still sound like single coils. So Holy Diver/Trilogy/Trilogy gets my vote :)
