Wild rose makes good shafts, and they stay straight as well as any shoot shafts if you're picky cutting them and make sure they're well-seasoned and then heat-treat them. Pick shoots a little bigger than you think you'll need-they shrink as they dry, and the bark/cambium comes off which further reduces the diameter. You can pick ones that are a little bigger and plane them down to size. Wild rose checks easily, so it's best to let them dry a month or two with the bark on before peeling them.
