I Really like my Valentines, and I know what you mean about the pickups.   I have contemplated swapping the pickups out for HSP90 Mississippi Queens.   I have a MQ in the neck of my PRS and it is fantastic.   But I keep going back to the idea of leaving my EB alone… because it’s great the way it is.    Wish I had your problem, having 2 great guitars.   Good luck, and let us know what u decide, would like to hear about the outcome.
