OP here.
Found a perfect match: the DiMarzio Titan. Also has a brass baseplate like the PAF Pro, I always think HB's don't sound good together if they don't have the same base plate material, but it could be my imagination. Either way, the Titan sounds good for a variety of styles, not just METAL, which was a great surprise.
Tried the Dreamcatcher too but it's a very different beast, got a bit of that notched-wah thing going, sounds good but doesn't fit the PAF Pro at all.
This channel covers a wide range of HB comparisons, which was very helpful. I found few sounded better than the PAF pro with the setup used there, except for the Titan, and indeed, it matches the PAF pro so well.
Have fun!
