It's hard to get a true straight grain dowel. Much more work than necessary. If you think about it, the arrow is much like the bow as far as energy transfer/storage is concerned. A dowel has many potential imperfections and violations to consider. Much time and waste occurs to find a good one for the purpose. A shoot, however, is a naturally produced shaft that, once straightened, will provide amazing results. the best thing I've found is that they're free and unlimited! They're also fun to harvest. Not that much work as a dowel and much more gratifying!
