Elixer Optiweb Coated Strings are so good because Firstly, they give off a very bright, yet warm resonating tone. The Optiweb gives it a nice and natural feel, providing a unique playing experience to the handler. Furthermore, the coating actually helps against corrosion and debris buildup. This allows for the strings to have a longer lifespan than the other coated or uncoated variants. Furthermore, regardless of it being coated, it sounds just as great as it was uncoated, so you don't lose out on any of the nice sound and tonal characteristics. The strings also contain an anti-rust plating, which maintains the tone's lifespan throughout the duration of using these strings.
