Just realized what your nickname here is... of course you should get blades!!
Now that you've elaborated on what you're after, I'd definitely recommend single coils. Big Blades are single coils, as are of course Big Singles. If you can stand the hum...
The best hum-cancelling design that gives you most single coil tone is IMO/IME split coil. Big Splits get you real close to Big Singles. In fact, some P pickups can get really close too... Like Wilde P46. (I imagine the Nordstrand P with angled poles might be similar)... not all P pickups are thud machines (also depends on strings and other factors). That said, a personal "pet peeve" is that I cannot embrace the unbalanced 5-string split coil design, because one coil has to sense 3 strings and the other coil 2 strings. While all reports say that they are effective at hum-cancellation and sound good, my OCD or whatever just says no

That's where Big Rigs or Zen Blades could work well, but they are smoother sounding, and at that point you might as well use single coils and live with the hum.
Note: Fat Stacks allegedly have a killer single coil mode. So it's like having Big Singles, but with an option to get them quiet in stacked mode. Worth considering, especially in an active bass (stacked mode seems to benefit from a preamp).
