Professional
A beautiful string with amazing versatility.
Pros: The string makes a beautiful sound overall while also giving a mellow deeper effect than any other I have ever used. Harmonics are easier to achieve and playing in very high positions the quality of the sound is still excellent. Playing a difficult piece with many double and triple stopping eg Cassado Suite for cello solo was easier to achieve.
Cons: None.
Other: Rosin does not seem to cling to the string -it clears quicker and thus a more constant sound is achieved.
