To answer some of the questions, oak is not on the list because it seems prone to warping. My guess European Pear is not used because it doesn't look interesting. The carbon suggestions are interesting, but not for a DIY kit, certainly not for an inexpensive one. I am concerned about the dust machining would cause on CF. As far as wood combination, inlays, etc I will leave that to the builder since my taste might not be necessarily the same as others ...
