I'm not sure if you wouldn't like the Aftermath. From what I heard it sound like a good diverse pickup as well. Below are a few links. Two of them are Nolly's Clips, which I believe show how you can get a tight modern, and crushing tone. The last one is Eric's YouTube clip, ant it has more of a Heavy rock tone. They are both the Aftermath, but completely different tones.

http://www.youtube.com/watch?v=ztsnOsNe8vkThe only way to know is by ordering them, and trying them out. If you are not into it, then you can always exchange it. That actually happened to me. I ordered the Nailbomb Set with the Ceramic Bridge. Though they were super kick a$$ sounding, they weren't quite what I was going for. I now know that I am into really more mids in my pickups.
Before you decide to do anything, If I may suggest, do all the research you can do on it, listening to audio, asking the good folks on this forum, too. After that, ask send an email to the BKP team. Tell them what you are trying to achieve, the kind of guitar you have, and signal chain that you use. They are extremely knowledgeable, friendly, and they desire people to be happy with tone.
Of course I am totally assuming you don't know that info. In case you do, my apologies.
