You?ve heard it before, line control is everything. It is THE thing which makes a cast work, proper line control.

What does that mean?

You?ve made a nice forward cast upstream and you?ve retrieved your fly line as it comes back toward you. Now you?re ready to make another cast. Just like trying to move the lawn sprinkler by grabbing the hose and pulling it, the sprinkler doesn?t move until all the hose between you and the sprinkler are tight - until all the slack is gone.
