We use 80/20 because WE like them on OUR guitars... once YOU buy a Taylor, it becomes YOUR guitar and YOU can put whatever kind of string on it that YOU desire. Be careful to not over think this one, it's subjective and we all like what we like. Also be careful not to believe that 50 people on an internet forum represent a true sampling of the almost one million Taylor players worldwide.BTW - I sound better playing 80/20...
