I've never made an HHB bow.  It doesn't grow around here.  I did get an HHB bow in the PA Bow trade a few years back, made by Greg B.  Excellent bow, both in the woods qualities and the the construction.  So I am a fan of it if you can get it.  Hackberry here grows from the cracks in the sidewalk, along nearly every fence line and bar ditch and waste area.  I tried it years ago, before heat treating was a thing, for me anyway.  It was junk before it got to full draw due to the excessive set it took.  Toasting the belly changes the equation entirely.
