Cold Sweat neck matches very well with PK bridge (actually it matches well with any of the contempory bridge models) - it has nice cleans but is powerful & punchy enough for lead work. I have a PK/CS combo in my Jackson KV2 & they balance really well together.
The PK neck is great for noodly lead work, but its cleans are too powerful & aggressive for my tastes (it's the only ceramic neck pickup BKP make FWIW).
As an alternate suggestion, I think the VHII neck is absolutely GREAT. Similar level of power to the CS, but a thicker sound with more of a "vintage" neck tone, as opposed to the smoother more modern sound of the CS. I've matched it with an MM & NB bridge successfully & IMHO it would balance fine with the PK. It's hard to say which has a "better" clean or lead tone, but to my ears the VHII has more of a "chime" to the clean sound & a slightly "bigger" more dynamic lead sound.
