I replied to your PM, somehow missed this thread though!
Yeah the Black Dog is what you seek. It gets ultra heavy if you need it to (I wasn't even taking my 5150-II past 4/10 preamp gain with the BD), but is a great clean pickup and of course does all that PAFfy stuff perfectly. Pinch harmonics were quite tough (and I'm quite a heavy user of those - I don't miss too many).
I have since moved my MM into the baritone (I wanted to mix things up a bit), and I have to say that also slays in there, even down to E-E-A-D-F#-B tuning (although a PK or Aftermath may suit me for that slightly better).
I have to say I didn't find what Tim says about high gain pickups in Baritones - I love the MM in there!
But for your requirements, BD all the way :)
