Rob, I'm not Jim, but we did just finish a 7' 8" Knabe with three bridges. In spite of my general dislike for copper wrapped tri-chord strings I did keep that configuration on this piano. The performance was acceptable, but it did confirm all of the reasons why I don't like them on pianos of this, or any other, size. We have another Knabe of the same size and type. This time I will be converting that section to bi-chord wrapped strings. The speaking lengths are much too short for plain steel strings. With the bi-chords I can blend unison tensions, string impedances and inharmonicity much better than is possible with tri-chord wrapped strings.
