Yet another update:
Jens Ritter sent me a set of lower bridge saddles. But they weren't high enough above the rest of the bridge assemblies to allow the strings to clear the bridges on their way to their anchor points, on the A,D, and G strings. I don't like when the strings touch the bridge behind the saddle. I don't know if it's really a problem, but it just seems like they shouldn't touch there. The old, taller saddles worked for the A and D strings with the bridges in their lowest position, so I put them back. (The string height at the 12th fret is now 6/64ths of an inch for each string, which is acceptable to me.) But the remaining problem is the G string, which passes throught the slot on the saddle and lays flat on the rest of the bridge assembly until it breaks for the anchor point. I think I will turn the saddle over and cut a shallower slot in it and see if that works.
