Willie: on the contrary! I'm delighted this topic sparked so much conversation. Keep it coming!
Aussie: thanks for all your time collecting and sharing your knowledge. Valuable stuff.
Badger: At the risk of making an arrows post in the bows forum, see attached PDF for some arrow wood properties. To compare overall suitability for flight arrows, I made up something I'm calling the "ballistic index", which is a measure of density and stiffness relative to POC as a reference material. Lighter, stiffer woods get a higher score. In terms of pure stiffness (MoE), Greenheart is the highest I've seen. Bulletwood, Ipe, and purpleheart are up there, too. I'll make a post over in the arrows section to avoid getting too far off topic over here.
