I actually like the stock ones quite much. Especially clean, they had that great clean "PRS" sound, it's hard to describe it.
For high gain I'm very satisfied with the bridge pup. Tight but still dynamic. I do play in Open C tuning and with high gain, and these pups handle it brilliantly.
For what I can tell, it-s not really what you are after, but let us know what you get and how it works out!
I ordered CTS-pots together with the pups from BK. Both push pull, one for coil tap, and one for phase change.
