I haven't tried the tree-of-hell, and have no plans to. I've cut thousands of them down, though-it's light, spongy, wierd wood, and it has a horrible smell. Causes contact dermatitis in some people. Like Pat said-kill, kill, kill. It's one of the worst invasive Asian trees, takes over whole ecosystems and produces alleopathic toxins from its roots that prevent other plants from growing (except other Asian invasives). The Paulownia is a really troublesome invasive, too.
