Board bows can be as good. Tim baker proves this time and again. I will prove it when I post my latest maple bow in a few days. This is not a "way off" opinion. I usually work with osage because it grows everywhere where I live, but I wanted to see for myself how good I could do with a board. For any new bowyer out there, buy a board, cut a tree, it's all wood. Bottom line, you don't need backing and you don't even need a stave split from a tree.
