These strings are super-responsive without being unpredictable. A light touch produces the round warm tone I'm looking for, but the strings also allow me to dig in with the bow without crunching or distortion. The set is well balanced and I found no reason to swap out the E string. The strings settled in quickly and after the first two days I've hardly had to touch my tuners. My fiddle is very happy with these strings. I'm not sure it has been happier!
