I've got two bows tillered and shooting them in now, then I'll pick one for the trade based on the results of shooting them for a while. One is osage backed with bamboo, and the other is hickory backed with bamboo. I know the hickory one is absolutely bomb-proof based on a couple other BBH bows made from the same hickory tree. The BBO is made on a piece of osage from a new source that I haven't used before, so I want to shoot it for a while to see how it works out.
