VHIIs are really awesome pickups, I have a pair in a Kramer, and they are beautifully open and fat sounding. I believe they are proper vintage spec PAFs, wound with as many turns as you can fit onto the bobbin. My bridge VHII has a double row of screw poles, so should have marginally more low-end focus than the standard version; I've not compared mine directly to the ordinary model, but it is a very cool pickup for sure.
Tim always recommends the VHIIs to people who drop tune, as the lower output keeps things extremely clear and woody sounding (FWIW I remember him saying that he put VHIIs in Jon Schaffer's baritone guitars). You won't get the same huge low-end thump that you might from the contemporary BKs, but you will definitely get a uniquely responsive and open sound.
For the neck partner, I wholeheartedly recommend the VHII neck pickup - it's absolutely beautiful sounding. It's a PAF that's hot in the right ways, while not sacrificing any of the open-ness or chime. Tim convinced me to stick to the calibrated set with the VHIIs, and I'm very glad I did.
