How much do you really want to know? I am a builder and an "acoustics junkie." Are you interesred only in sound or also in stability...or cost vs. avilability, or are you interested in proper drying and storage techniques which can render a fine piece of wood worthless? Would you like to know the densities and the coefficient of dimensional change for various tonewoods? Would you like to discuss grading and cutting from either a block or a billet and which will minimize the runout and why runout is so detrimental? Or are we just talking D.nigra vs. D. latifolia?
Not being smart gang, but the market is consumer driven and there are advantages and disadvantages to all tonewoods and a lot of stuff to a luthier ends up as a trade-off. What's really important is the playability and sound of the instrument---guitar, fiddle, Hammered dulcimer, or mandolin........Play it yourself and have it played along with others with your back turned.
Quite seriously, I'll get into all of this, as I suspect Bill will too, but you get to writing a book more than a post!!! If you're really interested in the subject and how a luthier looks at it...happy to oblige.
