We've been through this again and again and again on this list, and my opinion ( which will be ridiculed by some here, but I have no interest in further defending ) is that old wood that has been in decent ( reasonably clean, dry ) environments is acoustically superior. ( As in: "Rich" and "Warm" sounding. ) But this superior resonance can not be expressed, when the crown has imploded. I'm doing my first full soundboard recrowning according to a new method ( not yet discussed here ) and may report the results.
