Daddario NW054 Single String

I've always used these strings. Some say that they get oxidized easily and talk about other brands but it all depends on environmental factors, sweat and whether one wipes the strings after each use, amount of time they are played, etc.

I always go back to D'Addario because of their vast assortment of gauges and especially their 'balanced tension' sets. Other brands don't always provide strings of certain gauges and definitely not balanced tension sets.
