This is my understanding as well. I also find that when I find old paper
leader, it is often brittle, unwieldy and slippery --and a bad friend of
adhesive, as Tom Fine points out.
However, I admit I do not know how to look or listen for potential problems
arising from electrostatic charge in leader tape. If anyone has found these
problems, I think the class would probably like to hear about them.
