The approach
Start with the right question.
Experiment with speed, pause, angle, profile and presentation distance before buying another bait.
In practice
Make it useful on the water.
Describe the observed response so you can tell a refusal from no fish present.
Keep learning
Connect the dots.
Use this guide as a starting point, then compare it with the water you're fishing, the tackle you're using, and your own observations. Good fishing knowledge grows through real practice.
