No slack line can occur during the casting stroke.
You can’t make any cast until you have the line end moving.
You should lift all of the line from the water before making a cast.
- Do not actually wait for the tug on your back cast before starting
- the forward cast. By then, you’ve lost the constant tension of the
- fly line and added slack as back cast falls.
- It’s OK if your line hand is slightly lower than your rod hand as long
- as both hands move in unison, and an equal distance to each other,
- during the casting stroke.
