If I had to pick only one wood to make bows, it would be osage... hands down. Osage does it all... backed (with ash, hickory, maple, or bamboo) board bows, stave bows, character bows, ELBs, war bows, flatbows, R/D bows... narrow, wide, flat, stacked, round... osage does it all. It's dense and strong, doesn't break easily, and takes little set if you do your part. Only down side for me, it doesn't grow here.
