String Rating (Hide Explanation)

Many manufacturers are now quoting values for various characteristics of their strings. These characteristics cannot be taken in isolation as any particular restring should take into account several different factors. The most common characteristics are:

  • Comfort - how comfortable (touch, feel) are the strings to play with?
  • Durability - how long can you expect the string to last before breaking?
  • Spin - is the string designed to help with spin production?
  • Power - how powerful is the string?

Where the manufacturer doesn't quote figures for these characteristics, we have inserted our own, based on our experience and comparing with other similar strings.

Please note that as these ratings are manufacturer based, they may not represent an accurate comparison between brands.

Each set of ratings refers to only one gauge of the particular string as the rating will be different per gauge. This is indicated by the text "(Ratings refer to xx variant)" after the ratings.
