String Brand Notes - Iso-Speed

This company in Austria produces a limited range of tennis strings under their own brand name. They are also believed to produce strings for HEAD which is also an Austrian company.

The strings are worth considering, but some care is required. The top string is Iso-Speed Professional which has a good response, but obtaining the correct tension can be a problem. There are other strings in their range with good performance and are liked by some players.

The company was requested to provide strings for testing, but so far have not done so.
