The method is described in
five steps, but here are a few
additional tips. Practice on grass
rather than pavement or to avoid
damaging your fly line. Make side casts
low to the ground, not vertically. Make
sure that your line-hand follows your
reel and that your two hands are no more
than 12 inches apart.
Try not to haul more than about one
inch. If you make the moves correctly,
the line will zip back behind you. As
the line falls to the grass behind you,
your hands should remain within 12
inches of each other.
Analyze the backcast before making a
forward cast. It is vital during this
learning session that you move ever so
slowly back and forth prior to making
the haul and speed-up-and-stop.
Most people have trouble coordinating
their forward cast with their haul, but
if you stick with it, it will soon come.
Continue this exercise until you are
hauling correctly. Once you feel you
have it, try false-casting and making a
double haul. If you have problems, stop
and do the exercise on the grass again.
To further improve your double haul,
use just your rod tip. Working with a
short rod magnifies any casting flaws.
As you learn to make the brief speed
stroke and haul simultaneously, you'll
find your cast improving. Improving Your
Double Haul Watch a hundred fly casters
who use the double haul under different
fishing conditions. Rarely will they
change the speed of their line-hand on
the haul. When you haul with the
line-hand, you accelerate the rod tip.
The faster the tip accelerates and
stops, the farther the line can travel.
Most fly fishers make all their hauls at
the same speed.
To make longer casts, most casters
put more force into their rod-hand
instead of concentrating on increasing
the speed of their hauls. Consider the
double haul to be like a gear shift.
When you need more speed, change gears
and increase the speed with your haul.
Don't increase the length of the haul,
just its swiftness.
To shoot line after you have made a
quick rod stop in the forward cast,
release the line from your line-hand.
Make an "O" shape with the forefinger
and thumb of your line-hand and allow
the line to shoot out through it. To
stop the line from shooting too far,
close the "O" on the line.
