well, the best setup i found for single/humbucker active combo is the EMG pickup set. Now i know all you hardcore blues players are cringing at the thought of an EMG, but i, being a metal player, am very fond of the EMG pickups. I have played a little on them and from what i could gather in a short time was they would work for what im going for. A part of me wants to just go with seymore duncans all the way, and forget about active pups, but i havnt made that decision yet. Pickup choice is something that can actually be decided later in the build process. I usually dont rout the pickup cavities until very close to the end due to certain methods i use. I would ask you all for pickup advice, but since pickup preference is so personal, theres not much of a point.. haha.
