I've found the red-streaked stuff to be of very high quality. It seems like it has no inclination to take set; even when tillering mistakes occur. I cut my Osage on family land in Central Texas, in the bottoms of the Colorado River basin. Even though much of the Osage that far West grows as gnarly "scrub trees", if it's growing in creek bottoms & flood plains, or near springs, it tends to have extremely dense, dark summer wood rings, which are full of "lunar rings". It is within those stacks of lunar rings, that you will find the fiery red streaks, while sanding. Rare & beautiful!
