I was just reading an entire thread about how Ed Friedland recommends a reverse P on a P/J bass. He recommended to keep the traditional P if it's just a P bass. But he said the problem with having the traditional P on a P/J bass is that it puts the treble coil of the P pickup too close to the J pickup at the bridge. And he said the reverse P gives the bass a more balanced sound across all the strings.
I greatly trust Ed Friedland's advice, but I'm curious to know what everyone else thinks about this. I should be able to order my new Lull bass by the end of April at the latest (possibly by the end of March), so I need to make up my mind on exactly what I want. My only reasoning for keeping the traditional P placement would be to keep the bottom end strong, especially since I want a 5 string.
