Now, while I only use an Irish Tour middle (which is bloody great for strat sounds), I can tell you that generally, BKPs will be clearer and more defined than other pickups as mentioned here.
What that means is for one, that they donīt have distortion coming from the pickups itself. A lot of others have dirt already in the DI signal that comes from the PUs, for example dimazios and duncans. This leads you to hear them as hotter, while the effectivly donīt really have more output. That means switching from those PUs to BKPs will usually involve turning up the gain, cause they seam to eat it. This will ultimatly give you a lot more detail and defintion in the sound, let me assure you. This makes them superiour for chords under gain and all.
Itīs hard to explain, but this is something you can expect from BKPs in general over duncan.
Btw, I think while biased we are still very tollerant here too. We tend not recommend anything but BKPs but sometimes a Duncan is just what works for you, so that is what we tell people looking to upgrade pickups sometimes if they did not like BKPs they tried out.
I for one also still love my Dimarzio Liquifire and Crunchlab (though I have not tried Ceramic Nailbomb and Coldsweat neck combo yet).
Oh yes, and I think you would do very nicely with an IT set (baseplate on the bridge probably).
