over the left shoulder in the back cast and over the right in the forward cast. This is a very pretty and very smooth cast much used by fly fishermen of the old school. Tournament casters use the straight backward and forward cast.
The back cast ends when the rod reaches the perpendicular or when the thumb lying along the rod is pointing straight up. This brings the active rod tip slightly behind the perpendicular, which is correct.
The Pause
The mistake most often made by the novice is to assume that the forward cast immediately follows the back cast. He forgets the pause and thereby " bunggles " his cast. The pause is a very important stage in the process of casting a fly. Its object is not entirely to permit the line to straighten out behind, and thus avoid snapping off the flies, as most writers claim, but to permit the back-traveling line to exert its weight and force and put spring in the rod tip for the forward cast.
