Against my better judgement because I thought we put this to rest about 400 years ago (Sudbury bow; found circa 17 the Century; made from hickory; stored in Harvard's Peabody Museum). Pat I think your remarks were outstanding. Osage and yew do not grow around here. They are great bow woods. However, there are other bow woods that also work really well. I've used a variety of woods. In fact, I've made bows from all of the standard woods and then some.
JD you said:
"Yew and Osage:
1. Work well with traditional hand tools. Cut, scrape, rasp and sand easily and efficiently. (So do whitewoods.)
2. Are very elastic, strong in tension, and strong in compression (all at the same time) making them: (True enough for osage) Yew is elastic but medium in tension and compression; one's design for whitewood bows should compensate for med. elastic tension and compression; make them a little longer and wider; whitewoods poor in those factors should not be used and usually are not).
-Forgiving to tiller. (so is hickory)
-Adaptable to many different designs. (please elaborate; that hasn't been my experience).
-Longer-lasting. (see comments on Sudbury bow)
-Consistent performers. (please elaborate; consistency may be a relative term).
3. Are very rot-resistant. (As is black locust which really isn't a white wood; see initial comments regarding the Sudbury bow.)
4. Perform better though a wide range of moisture contents. (May be but a hickory bow at 5% will perform better than an osage bow at 5%. The osage bow may break at that level. Too low for osage.)
5. Are especially BEAUTIFUL. (I do like watching osage's color change. But so many stain osage bows because they ca not deal with its initial pale color; white wood bows can be us as pretty.)
Final comment- The bowyer should fit the design to the stave and not the other way around.
