For anyone who doesn't know or look this up, Osage Oranges are what we in the Midwest called 'hedge apples', those creepy alien looking green balls you'd see littered in yards.
But in the comments, someone identifies "speed of cast" aka "self-fling speed" (!) as the key metric for bow woods, and he doesn't have European Yew, but according to that, Pacific Yew and Osage Orange are also pretty much the same!
After watching this, I made the connection that the French "Bois d'arc" for Osage Orange refers to its use in bows. It turns out that Osage Orange really is one of the best woods for bows.
Too bad they couldn’t do Yew too. That is another top bow wood.
