I use this string for arco playing, as part of the whole set, lately. It's looser, in a gut way, & in a gut-like direction, which I love than traditional arco steel we all know. As a top G string it speaks quickly, is articulate, & cuts through in the orchestra. Solo playing is very lyrical & harmonics ring on as you take a coffee break. As a con, & lover of gut, I'd love to see a slightly thicker version, whilst keeping the same tension. I'm looking forward to see how it ages & settles in. Bottom line: these would be a great audition string.
