I've seen it often enough, that it's kind of quit being too big a concern - when it's done well. Reality being the inconvenience it is though, agraffes, or half agraffes would maintain unison spacing and leave more flexibility in (mis)locating tuning pins. Sort of a belt and suspenders approach. That serves the una corda concern ok, but tuning stability? Ron N
