This is my experience as well. I have a guitar with a P-rail set and the triple shot rings. I sometimes use the bridge in series humbucker mode but 90% or more of the time its just in P90 mode.I had one P-rail neck wired up in a Carvin CT3M and found I really only liked the P-90 sound. I also, found the P-90 sound to be very balanced and polite , not really nasty and raunchy. YMMV.
