Wood arrows are all I've ever used in more than 50 years. I won't hunt with anything but wood....and they've never let me down. Going back decades ago, I stocked up on cedars buying them by the hundreds for myself and growing archers in my family. Bought them by the hundred lot, much sorting... weighing and spine checking. Affordable to me back then at about $50-70 a hundred. The old days some on here surely remember.
Nowadays, your best bet is surewood and wapiti , I know of no others raw shaft suppliers for a dozen matched spine and weight. Good luck, ain't nothing compares to to a well a well crafted wood arrow.
