It's a long time ago, but if I remember right, the PAF Pro sounded relatively bright in the neck position of my Hamer Vector (I had a MegaDrive in the bridge). Not much bass but, as suggested, strong on high notes.
I wonder if the VHII neck, with its staggered coils, might be a bit too "open" and/or bassy? I'm thinking maybe the Cold Sweat neck would fit the bill quite well.....? It can sing and sound sweet, but it's got a little more power than a vintage style neck humbucker.
(The Nailbomb or Holydiver neck models might be worth considering too, but I haven't tried either so I could be barking up the wrong tree)
