I have been using these strings for many years on the advice of my senior colleague from Chicago Symphony,
and I recommend them to both, professionals and students.
Good value for money for the middle class of violin. Although, I use the E string by Wensminster.
I replace them approximately once a year when I play a few hours a day on the instrument.
This is a very good choice!
The aluminum winded E string seems ok. May be easier on the fingers.
