Sounds like a Hammer production movie, but what I am really thinking about here is a means of directing a backcast with great accuracy. This is what we do:

• stand at right angles to the intended direction of cast (open-stance)

• rotate the forearm from the elbow so that the thumb is below the rod instead of above it and the palm is facing outwards - or to look at it from another perspective; rotate the rod so that the reel is pointing skywards instead of downwards

• make a backcast

• during the pause rotate the rod 180 degrees, so that when we make the forward cast our thumb is behind the rod once again

This I find produces a very accurate backcast which can be sent between trees with confidence. It is also useful for sending high backcasts over dam walls, hedges and other obstacles.
