I use string ties in all my guitars and, yes, Jon, they do work fine. Compared with the traditional string loop, the string tie ensures an higher break angle from the bridge bone. I use Diamond string ties, though, and you can acquire them at GuitarrasdeLuthier in Madrid. A set of seven pieces costs € 15,00 or € 18,00, depending on the model.
