'78 Pbass Pickup help

Hey,

First post.

I'm building a new rig for a Pop/Rock project. Here's the rundown.

Ampeg SVT2 Pro
Ampeg 810E

I just picked up a '78 Pbass, it's in good playable shape ( all original at present).

I'm not concerned about resale, it'll be a players bass. I'm doing the setup at present ( badass II bridge replacement).

the stock pickup isn't soundin very good, so I'm lookin at a replacement.

I've read through all the archives on pbass replacement pickups, but it all comes down to opinions unless I mention what I'd like to hear.

Here's a clip of a tune where the bass is in the direction I'd like the sound to go ( this was recorded with a '74 pbass)

So, it looks like my pickup options are:

Fender '62 reissue
Rio Grande Muy Grande
Rio Grande Vintage P
Seymour Duncan Quarter Pounder


Any direction appreciated, otherwise, I'm just gonna have to start goin through them until I find "the one" =)

Regards
