Seasoned wood is the only way to go, IMO. Even if you get kiln dried lumber, it has to season. Let it sit and you will make much much better arrows. We have some that we made up from what I make that are over two years old now, and they are just as straight as the day we made them. And we have yet to break a poplar dowel on the grain run out. I have two or three that we made up with over 12 run outs on the dowel just to try. Trust me, they have missed a lot of targets, and are still straight and shootable.
