Tonal differences between Bartolini 9CBJD and 9CBJS pickups?

I've been looking into these Bartolini pickups. I know I want to get the #3 set, but not sure which version.

Is there any major tonal difference between the dual-coil and the single-coil ones? I'd imagine the JS would be closer to a true J bass pickup and the JD would possibly be fatter?

 

Yeah I'm not expecting it. But I'm not exactly chasing it.

I ended up contacting BestBassGear and they were really helpful. They confirmed my hunch that the 9CBJS would be closer to a clearer, true single coil sound, while the 9CBJD would be a bit more fatter and whatso. After what they told me, I decided I'd go with the 9CBJS Bright set. Sounds like it would give me the best of both worlds, so to speak. The modern scooped clarity and brightness, and the classic growl/grind of a single coil.

And just because I have another J bass, I ended up getting a set of Duncan 1/4 Pounders. I actually dug the clips I heard, and it's on the other spectrum. Modern, but more thick and grindy. Something more in-your-face since this bass will be tuned to drop C.
