Calling for Wood ID Experts

Ok you Tree ID Guys what do I have here.

I took down a clump of 5 of these mangy, skinny, somewhat tall trees and thought I was dealing in some garbage wood (which can still be the case). These were beasts to pull out of the ground - the tap roots went straight down and all roots were stringy and very hard to break through - it was kind of comical as I thought it would take a hour to push them over and four hours later I was still digging.

Anyhow - planted a axe into on of the side and found very dense wood. So I am thinking my work wasn't in vain - can someone school me as to what I have here?

Thanks for the ID- yep - thats what have - wow - just did a little research on the Tree to Heaven and how evasive these things really are (kind of like a zebra mussel for the woods).
I also on the fence if it is even worth it to burn in my stove. Everything I read about this tree is bad. Glad I ripped it out. Funny though since I have also read I will see shoots spring up even if I rip out all the roots.

As to why I dug it up - I hate stumps and love to put in seat time on my Kubota.
