Before this conversation runs too far amok..........String selection has a lot to do with the individual instrument, player's style, type of music, etc., along with personal sound preferences. If you're going for volume with a dreadnought or a jumbo and you like the sound etc. of med. gauge phosphor bronze....Its unlikely you'll care doodly squat about S&S!!! Then again if you're a finger stylist with a OO, S&S might suit you just fine.
