Also consider a Cruiser in the middle position if you want something hum canceling. It has more power than an Area 67 and might pair better with your humbuckers. Plus since it's 4-conductor you can wire it to split with the humbuckers, although I think you'll want a different switch for that.
Honestly, the Area 67 sounded and felt hotter than a Cruiser, to me. The Dimarzio specs don't really back this up so I don't know what to make of that, and it's possible the guy who installed it screwed it up (this is before I really got the hang of soldering pickups) and wired it parallel or something... But the Cruiser Bridge pickups felt REALLY underpowered, to me.
Sounded awesome, unfortunately, but just couldn't keep up with a bridge humbucker, whereas the Areas could. And I know this is Timmons' preferred setup, and this was WITH an AT1 in the bridge, but I have to think he just wanted his singlecoils to be cleaner than his bridge humbucker, whereas I wanted the perceived output to balance well, so...
Anyway, if I wanted a Dimarzio to balance tonally with a neck and bridge humbucker, I'd try this:
Virtual VintageŽ Heavy Blues 2 | DiMarzio
On its own, it was a little dark as a neck and middle singlecoil... But, next to a neck and bridge humbucker, it'd probably sound pretty balanced.
