I have lost count of how many std PRS pickups that I have changed for customers! I have not played or heard the 57/08s so I can't comment on them, what I will say is that you will achieve a much improved sound quality with a BKP product over what you have, I prefer AII or AV over AIV! it's just my preference, I'm not sure if AII Stormy Mondays would have enough power for you, however they do sound "right" to my ears for the paf thing, I have heard some say that the AV mule sounds great in the bridge spot, so maybe that paired with a Holydiver or a Crawler with a VHII neck! I have all these pickups in simular guitars so I get a good idea of what should work with what, or just ask Tim he knows his products.
