I get my bamboo arrows from John at Glacier Traditional in Montana. He makes great bamboo arrows. I'm surprised how well they shoot out of my 45# longbow. I got them because I heard bamboo is "nature's carbon" and supposedly much tougher than wood. So far so good, none have broken, splintered or showed any stress cracks after about a month of shooting them in my backyard, whereas my wood arrows begin to show stress cracks usually by then. I recently ordered some flu flu bamboo arrows from him for my 30# self bow and can't wait to see how they shoot.
Oh, and they look great in my cheapo hand-made bamboo quiver I made out of a 3" diameter bamboo pole!
