hardest part for me is just picking a stave. I have hickory, ash, osage billets, character osage staves, and some hickory backings, walnut and hickory slats for tri lam bows. Have no idea what to do. The hickory is the best as far as clean straight staves go but hickory needs to be babied (kept dry) if going to be shot frequently. but i love building bows out of it.
