Someone did a poll on here just last week on that question. If I remember correctly, wood accounted for about 40% of the arrows folks use, carbon just a little less, and aluminum less yet. (My recollection may be faulty. If so, someone correct me.) It seems carbon may be taking a bigger bite out of the aluminum market than it is out of the wood market, at least for now. All the materials have their advantages and disadvantages. I've been shooting wood for more than 50 years. Think I'll stay with it.
