I just swapped out the split coil Seymour Duncan Basslines 6 string soapbars on my bass. I replaced them with Delano dual-coil pickups. The sound from the Delanos is just awesome. I paired it with an Aguilar OBP-3 and the bass sounds just like a Roscoe but even better plus the girth and muscle of the Aguilar preamp. However, I have noticed that there seems to be more string tension than when I had the split-coils in there. I'm using the same set of strings and have not changed them. (D'Addarrio XL nickel). I particularly like D'Addarios because they have less string tension than most others. Nothing else about my bridge setup or action is different and its all the same as before. Is it possible that because the Delanos are dual-coil that they will exert more magnetic pull on the strings thus increased tension?
