From what he says, he step routes the cavity so that it matches the underside profile of the pup exactly so there's simply no room for play unless I wanted the pickup to get closer to the strings and if anything I'd want to move them down a bit.
I'll just learn to like the white/black thing. I always thought they looked cool on a painted top where they'd provide some cosmetics but not on a nice flamed or quilted guitar where I think they distract from the top.
At the end of the day no biggie. Thanks guys.
