Review: Poor design - I have used the Black Code strings on many occasions in the past and was a total convert to them. This time I thought I would try what in mind was an upgrade. Not so. The strings are square in profile and when installed they lay flat in the racket not much access to the sharp edges. If the string had been made with a twist in the string I think they would have been great. But sadly they don't.
