I've used the nanoweb Elixer strings for years and can't imagine switching!! If you always have your guitar out and ready to play these are the best! I live in a humid climate that just eats strings up quickly!! It's hard to get a week or two out of a set of other strings before corrosion sets in and makes them flat sounding even when in tune!! Elixers last months longer than any other strings and retain that crisp brightness of new strings amazingly longer than anything else I've tried. The nanoweb coating is thinner than the polywebs and I prefer that for touch and feel but the coating is negligible while playing. The mix of light-medium strings over a super bass vs treble balance that I prefer. Like the other reviewer states in really does provide a piano like balance in the sound.
