As an hobbyist bowyer you're pretty much spot on for bow woods. Osage orange is generally considered one of the best bow woods. High-quality yew is usually considered the ultimate bow wood, but it's very rare. Elm, dog wood, and ash are pretty popular too.Sitka spruce. We build airplanes with it. Strong, light, and stable. Douglas fir is also crazy strong, but it's heavier. Our propellers are made from hard maple. Very tough, very strong, buy when it fails, it shatters. Love your testing device!
