+ 1 for the Alnico II Stormy Mondays, especially as the absence of the permanent neck / bridge phase cencellation ( as found in the P.G. set ) - will allow the 'usual' range of Gibson toggle switch options/ sounds from your Les Paul.
The only caveat is that the Stormys sound brighter in a maple top Les paul than an all mahogany guitar, so you might want to consult with the mighty Tim to be extra sure. I am not sure if the P.G. set are wound darker ? Mine currently reside in an S.G. Standard and they are very sweet and smooth if I roll the neck P/U tone back a bit - without any loss of clarity.
Do remember that I usually play very clean, so if the Stormys are driven through a mid rangey overdrive or driven amp, I can imagine the bright but rounded tones will balance nicely.
Meanwhile there is a good demo of Stormys in a Les paul on 'You Tube' done by one of the chaps here - and the part where the neck pickup is used to play bluesy sounds lovely.
I am a real convert to the Alnico II sound as heard in the S.M. pickups . :D
