The Last Bass Outpost

Got a bit of a dilemma here... I recently purchased  a Peavey Millennium 5 string bass  from a co-worker, and I plan on removing the fretboard and replacing it with an ebony fretless fingerboard. My dilemma is this: I want to replace the single coils with hum cancelling pickups, and have narrowed my choices down to 4. Bartolini makes 2 models- original bass and classic bass, and Dimarzio makes 2- area jazz 5 and ultra jazz 5. Does anyone here have experience with any of these pups? I have been searching the interwebs and can't find a decent review on any of them! Thanks in advance!

At the risk of getting flamed and my credentials as a bassist being pulled and being forced under pain of death to play nothing but guitar for eternity, I have to ask: What is this bass cap in a Ric that y'all are mentioning from time to time? I have only played one Ric in my short but miserable life and loved/hated it with a passion! Loved the way it played, but hated the fact that whatever I did to try to get that punchy 'Ric' tone, I failed! Wore blisters on my index and middle fingers in a 2 hr jam session. Forgive my ignorance, but I gotta know! Curiosity is gonna kill me one of these days...
