I've started using these--the medium tensions--and I really like these more than the Corellis I was using. Those were arco strings anyway. They plucked good, very clean, but the hybrids growl and I love that! I'll take growl over clean any day of the week. I was reading an interview with Christian McBride and he says he uses the same thing. I didn't know that before I bought them. I just wanted to try a different string so I ordered these from Lemur. A friend of mine loves them and has just ordered a set of light tensions. Can't wait to compare them to the mediums. Anyone use these and what do you think?
