Thanks to all of you who had suggestions on bridge pin replacement. I got a set of rosewood pins and used two to replace the top two bone pins to tame the shrillness of the B and high E strings. The verdict: it's an improvement. I'm not wincing at high notes anymore. I might still try heavier B and high E strings to see what happens some day - it's fun to experiment - but there's no hurry. And yes, the improvement might just be my imagination. But my ears are happy, so I'm happy. Again, thanks!
