This is too subjective to rely much on other peoples' advice, case in point I love the single coil sound.
Not sure about Delano, but I would give Carey Nordstrand a call and ask him about sound and pickups. He knows a LOT about how both electronics and construction affect the tone and feel of a bass. Here's the contact:

He can advise you on off-the-shelf pickups, or make you a custom wind based on your tonal preferences. He also has a killer preamp, although you already have the Audere.
