Assuming these logs actually do have "superior resonance capabilities"--a debatable issue at best--this very characteristic would then make them totally unsuitable for piano soundboards. Which, as we know, really should be non-resonant. > > I'm sure the growth rings would be tighter on these old growth logs.

Tighter growth rings only means a slow-growth tree--not an old tree. But it is true that we will probably never see trees like this again. Slow growth typically takes place within an old-growth forest and it takes hundreds of years to create an old-growth forest. It's not the most economical way to create fiber. And maximum fiber yield is where the money is.
