It can be a good idea to slow down the turnover of the fly at the end of the forecast by feeding some line back into the rod by moving the line hand out toward the stripping guide. This characteristically occurs when a six or eight inch haul has been used to add some authority to a cast for purposes of wind or control but slamming the fly onto the water will lead to a penalty or scare the fish. It works in a hurry. The effect is miraculous. I know of no better way to get people into the haul.
Many hauls are itty bitty things used just to turn the leader over or rescue a fading cast.
The monstrous powerful hauls for making the rod do its' maximum duty on a long or windy cast have soft beginnings and soft endings in the false casting phases so as to avoid the slaunchwise kick of the fly from an abrupt end of a haul. A great strong haul into the back cast with an abrupt end will let the fly bang around at the end and waggle off to the side whereas if the haul was softly ended the fly will stay straight and the loop will be in a single plane. An interesting discussion of the place of practice and casting skills is Presenting and Retrieving the Fly a part of the advertising for a resort in Belize. The current practice of including distance casting events in sports shows allows us to try our luck in the contest and to observe the winners as well. Distance casting has one undeniable virtue.
