Wait until they cast one-handed to 45 or 50 ft and do the grass drill; the haul only adds line speed. Lay out an 80-ft rope, fly 40 ft from each end, a blue cone mid-stroke, orange cones seven feet either side.

What the instructor says

• Start at the blue cone. As the rod passes it mid-stroke, pull down and return at once — a down-up.
• Short, with slack below the hand. Enough loose line that the haul pulls line, not the rod; long hauls open slack and return late.
• Drill ladder. Hand only, mirror your hand, your hand moving theirs, then haul on the cone.
• Eyes closed. When the rod bends, haul; the loops come out better than when they watch.
• Into the air. Cast without a haul first, then add little hauls past the cone, tip up.
• Faults. Hauling before the cone, a long haul, no slack under the hand.

Putting it to work

1. Mark the rope and cones once, then film yourself to check the haul starts past the middle.
2. Reset the loose line under your hand before each repeat.
