The D'Addario black plastic strings are pretty much "normal" sizes..a lot of that type are bigger (La Bella, Pyramid, Roto). That's the main reason I opted for them, so I didn't have to open up the nut and bridge slots and mess around.
Having fitted them, they are just as nice as any other I've tried, and much nicer than the Rotosounds..which never sound in tune to me! The LaBella's have a bit more edge, the Pyramids are the softest and warmest sounding. But the D'Addarios are pretty much in the middle, nice medium tension as well, so haven't needed any truss rod tweaks in over a year of use.
