I have a five-string Elan with the P+J setup, and for me, the combination is perfect for Fender-style pickups. Of course the J-Activator is a stack/humbucker, so you don't have to sweat that 60-cycle buzz you could find in this combination with other pickups. For me there's nothing like that P pickup fullness with that aft pickup tone from a J, it's just way better for me than double J's.
Plus I just LOVE to wave it under somebody's nose while they're explaining to me why they bought a Sadowsky or a Lull or a Lakland or a . . . . There's lots of good neo-Fenders out there, but I always prefer a neck-thru, and I'm a hopless homer for Alembic.
Hope you enjoy it !
