Innovation Braided Orchestral Strings are particularly well suited for bowing, as they have a smooth chrome steel tape winding. But the core is braided nylon, which creates a more “old-timey” flavour to their pizzicato tone. So they would also work well for someone looking for a good bluegrass string.
They have a deep, dark tone, which takes a lot of the brashness out of bowing. And the tension is optimized for bowing as well, when they were designed, Innovation focused on the ease of sound production and articulation both for pizzicato and arco.
