I like HiBeams on my fretted P and fretted J. I just put Black Beauties on my fretless Jazz, and I think I became a better bass player instantly. IMO, they are everything a string should be. I originally played Ernie Ball Hybrids because Justin Chancellor (TOOL) uses them, and learned a valuable lesson....don't emulate anyone, choose what you like. That, and Justin is really insanely talented!!
