I've "crowned" three bridges, and found no benefit to it that I can hear, so I don't go th the trouble any more. Maybe a Philistine assessment, but that's what I have to work with. Mashing the potato chip to fit the rim doesn't bother me in the least. I stressed the wood in the ribs much more than that laminating in the crown. Oh, and a practical question about your being in the CC capital of the universe. When the RH% gets into the low teens, say 15%, the MC of the soundboards will be 3.5%, at or before which point a CC board will be flat or have reverse crowned. Do you have a recognized annual killer octave season or festival there? Ron N
