Ailanthus altissima
I was about to say the same thing! Catches fast, burns hot and lasts a good bit. Not long like real hardwoods, but good enough. I hate the damn tree, but I'd rather season and burn the straight grains stuff than haul it off. Smells awful, though, as I'm sure you know. I find that if you remove the bark and let season, the smell goes away after a few months. Splits real easy and makes for excellent kindling, especially when dry. No distinct smell to the smoke either. We've just about eradicated from our property, so I don't plan to burn anymore of it anytime soon, but it wasn't so bad while it lasted.
