I have used these strings since they were first available, and whilst I occasionally try other strings, I come back to these every time. They are stable, relatively long-lived and tolerate the use of altered tunings. I'd describe them as quick-responding and they really cut through the mix in a bluegrass or old-time setting. I know that steel strings are popular with most fiddle players of these genres, but These Karneol's work great for me and I often get asked what I'm using.
