(and one video, q.v.)
1. Always align your body parallel to the yellow rod.
2. Always aim the clubface halfway between the two rods.
3. Fade: the orange rod is the target line and the yellow rod is the swing line.
4. Draw: The yellow rod is the target line and the orange rod is the swing line.
All this is predicated on being able to hit the ball straight at will. Otherwise, you’ll just be adding more uncertainty to your game.
Practice these shots before you use them on the course.
Make sure the swing line points in a direction that won’t hurt you if the curve doesn’t come off as planned.
When you set up, disregard your target. Think only of the direction you want the ball to start. If you think of where you want the ball to end up, you will try to move the ball there deliberately, ruining everything.
The amount of curvature you get depends on the angle between the two rods and your ability to curve the ball. Experiment to find out your results.
