Another reason to avoid baffles is that they can introduce air currents into your light path.

Another way to get a really dark tube is to paint it flat black, then while the paint is still wet, throw in some sawdust and move the tube around so you get a good even coat. The sawdust should stick to the paint, and when everything is dry, put on another coat of flat black.
