Papa, not really sure. All the other woods I've worked with have there high points and low points, so to speak. All the white woods have a way of sucking up moisture like a sponge, which I don't like. Black locust is moisture resistant but is a little bit more fragile than some other woods and tends to very quite a bit between specimens. I've only made one bow out of mulberry and it exploded. I really don't have any experience with any tropical hard woods, I'm sure there are some good ones out there but they are hard to get in stave form so a selfbow made of tropical wood is unpractical to say the least. There really isn't anything out there that compares as far as I'm concerned.
As far as white hardwoods go I like Hop hornbeam, Elm, Hawthorne, Hard maple, and Wild apple. Not necessarily in that order but those would be my current favorites.
(notice I didn't mention hickory I have no idea how it got such a good reputation for bow wood I hate it. It does make good smoked chicken and backing strips though)
Soft woods, I've made bows of Yew and Erc. Of those two I like yew better. They are both pretty moisture and rot resisant which is a plus. Cedar is pretty unpredictable. It almost has to be backed with raw hide or sinew or it can blow into a million pieces at any given moment with out warning for aparently no reason. Yew is good bow wood but it doesnt like to be heat corected and it is still a soft wood which in my opinion makes not as durable. It dents very easily, and its pretty hard to get unless you live in the north west.
Steve, I got a osage orange sitting on my bar drying up right now. I'm planning on trying to plant some again. I tried it before and they all died. I'm not much of a green thumb. Don't worry I wouldn't retire. I 'd just be very upset.
When was the last time I even posted a osage bow? Dang, I don't think I've even worked on one for almost a year.
I need to get some yellow wood shavings a flying! I'm just putting the finishing touches on a HHB short bow right now. I'll be posting some pictures of that pretty soon.
