FnC, I am at the mercy of others on my info.It is definitely hard to beat "hedge". That's what we call Osage orange around here. That is some wicked stuff. I see sparks flying of the chain when cutting it with a chainsaw.Is it a big deal to mill that type of wood? I assume it would be cut with a bandsaw?
I use a small bandmill, and Osage is a #@!* to cut. A lot of it is how the blades are sharpened with hook, set, etc.
I had one customer bring me a wood from south America, can't remember the name of it off hand. It was only about 4- 5" in diameter and 3-5' long. A whole dump truck full of it at a time. You would saw it and when you get to the last 1" of the cut, it would crack the rest of the way to the end. It sounded like a high power rifle going off. That was always fun to do when someone was around and not expecting it.
