If the strings are too far apart the dampers fall behind the back action and disappear. No? OK, how about this: The ideal string spacing is such that when the bi-chord damper seats the tip of the damper is even with the bottom of the strings and not below. Wide agraffes combined with thinner upper bichord strings would get the damper sitting too low. However, the wide agraffes, which are usually used only on the lower few bichords, could conceivable extend farther up the scale. How's that?

Let me ask the question slightly differently. What is the advantage to using the narrow bi-chord spacing at all. Why not just go with the wide throughout?
