I can't believe no one has mentioned it doesn't get as big as most white woods and it frequently grows with more twist or character than most whitewoods. But I agree it's probably faster than osage with very low moisture content. I think it is more brittle than say hickory, certainly elm. I have popped a back ring a couple of times with hhb, where those little ridges form usually. One survived a with a CA repair, not even a wrap job which I adhore. I'd rather start a new bow than wrap a limb. Other I haven't tested again but it was a very high stress design, and a much large crack. If it's any measure of my opinion, hhb was the only wood besides osage I tried for the 58", 60# @ 28" "Ambush bow" contest. It is the aforementioned that popped big on the back ring. I don't think it would do as well, as osage, in a high humidy environment.
Can't say there are any real advantages over other woods though. Each wood, hell each specimen, has it's own unique strenghts and weaknesses.
