THE WORDS YOU CHOOSE MUST CONSISTANTLY REFLECT WHAT YOU ARE DEMONSTRATING. The path of the rod tip that causes a tailing loop should be incorporated into your general explanation as should the action of the caster that causes the rod tip to dip, and then rise causing the line to tail. The candidate may be asked to expand on their answer. Keep it as short and simple as possible. It is possible that you will be asked to demonstrate other ways to cast tailing loops. So do your home work on this one.
