I have always had to buy my osage, mostly on e ebay. I have also had quite a few guys in the forums swap me for some good osage. My favorite osage has come from Tennessee and Illinoise, some very good stuff from Michigan, Ohio and Mississippi are also high on my lst. My least favorite comes from kansas, missouri, and some other mid west states. I can't seem to tell the difference by looking at it. The density seems to be the biggest tip off for quality but I have had exceptions thier also.
