My concern with a double top is longevity: How will that top hold up 50, 100, 150 years from now? Any structure built up from layers glued together, and subject to vibration, will presumably come apart, eventually. What will look like in a double top? Loose Braces, detached bridges are usually relatively easy to repair on a solid top guitar, but will structural failure on a double top destroy the instrument? How do these epoxies hold up over time? Do they become more brittle? Maybe I've had too many instruments in need of significant repair, but I am concerned about how these double tops will fare with decades of use.
