Osage is just a different animal, be it for a bow or arrow Charles. I've made a couple Osage shafts that couldn't be straightened, period. You could heat the shafts, getting them super hot, and almost bend them double, and they would go back to their original crooked position. Physical weight is heavy, spine medium to light. Probably the more yellow/lighter color, low density Osage would be more suitable for arrows..........Art
