All I shoot are wood with the exception of bow fishing then it is a solid fiberglass shaft.
I prefer hardwood shafts; Ash, Hickory, Maple, etc. I have a few sets of arrows in Douglas Fir and Spruce and just a few assorted arrows in Cedar. I also have a few that are built out of Dogwood shoots that have stone points on them. The hardwood shafts are nice and heavy and more durable than anything else I have ever shot. Never had much issue in keeping them straight, just a little bit of tweaking every now and then.
