Hi CPIG and welcome to the forum.
It is a nightmare isn't it? Myself and my wife have several sets of BK's between us and they are all great pickups, responsive, clear and with more depth than anything we've replaced.
I'm not an expert on BK's, in fact the more I learn the more I know I don't know, if you know what I mean.
We have a cpig and to my understanding the ceramic gives you a tighter sound, and I think a bit more chunk. It's an awsome pickup and very versatile.
But I think you need to have a chat with Tim at BK, you've obviously been around the block with pups and he knows how to get the sounds, if a custom wind is required, he'll also be able to tell you if you are dreaming :)
The truth is you just don't know what will happen until you drop it into the guitar, one thing that will happen is you'll think "wow, where did all that detail come from" (even if it's the wrong tone ;) )
