Besides osage (and lowes red oak boards) those are the main two woods I make bows out of. Like pat said mulberry ain't really a white wood, but can be treated like one when making a bow if ya want. Although it does tend to have alot of pin knots, that sometimes give me trouble. Wheres as a hackberry tree doesn't even know the meaning of the word knot. Hackberry is about the most dependable wood for making bows you can find I would think in terms of consistency from tree to tree, most are all straight with few limbs till the top of the tree with no knots. If I could only have one it would be hackberry. If I was going to make a sinew backed bow though, mulberry seems to be good at that.
