I'm with you--I like PRS guitars for their overall quality, but I don't prefer the "modern" feel/attack of some of the CE/CU 24 pickups. So I took the 85/15 pickups out of my CE 24, and (while not 58/15 LT vintage-spec pickups) installed some DiMarzio Airbuckers--which are supposed to emulate the weaker and vintage-typical AlNiCo II magnets. I'll be honest, it saved a LOT of $$$ versus trying to source some PRS replacements...
I really like these pickups (Air Classic bridge in the neck, and Air Norton in the bridge) a lot in this guitar; in particular, I believe it's because I put a bridge-model pickup in the neck position. In 24-fret guitars, your neck pickup is in the "wrong" spot, so that neck position always sounds a bit off from a typical vintage tone (always a bit of bridge/middle sound in there). Well, I feel like I've been able to recalibrate that position by putting a bridge pickup there, such that the neck position seems more naturally-balanced than before.
