Don't listen Tom! :lol:
If it sounds good and does the job, no need to mess...
I have to admit, I'd take the Brow option and start moving pickups about, "just to see" (hell, I'm even in the middle of that process on strats :roll:)... but I can tell you what it leads to - more pickups, and then more guitars for the other pickups, and... and... :lol:
If you're enjoying it as is, play it as is...
I sympathise on the circuit board thing though... I personally don't like treble bleed caps, but I know some people swear by them... and sticking a quick cap in what you've got at the moment is, er, not quick!
EDIT: Sh1t! I've just realised - "I personally don't like treble bleed caps".... I've only tried them on strats (one, and I didn't like what I lost for what I gained) and teles (most, and I hate what they do in a tele...). I've never tried them on humbuckers... they might actually do a job for me there!!
