Never have I had such longevity of tuning until I,ve used the rib crowned and supported designs.

I hear from techs caring for my redesigns, that they are considerably more stable than anything else in the climatic vicinity. I'd expect that goes for Ron's designs too, and that certainly isn't a dead board talking. I think it's the laminated bridge caps not reacting to humidity like a solid cap does. In the case of your O, Joe, I expect the bridge surface has been crushed to the point that it barely reacts to moisture. Ron N </body>
