I would even go further to say that in cutting a bridge, a shade behind the center line of the pin is desirable as invariably the edge of the bridge top will gravitate toward the speaking length with some inevitable crushing of the bridge top.

Truly curious. None, except that the notch edge isn't in the speaking length. With the notch edge at or behind the pin, the pin is the termination as it should be. If it's solid in the bridge, the sound is clean. If the notch edge is in the speaking length, it interferes with the pin termination and makes the tone indistinct and muddy. A point I've tried to make for many years is that the pin is and should be the termination, not the notch edge. The notch edge can only get in the way. Ron N
