Overcoming drag (where the fly is
caused to drift differently than it would if
it wasn't attached to any line; which
basically means that the flyline is
travelling at a different rate to the fly) is
one of the most challenging aspects to fly
casting.
Drag problems occur every time we
cast across a river. Although some anglers
suggest that drag is not a problem with
subsurface methods, this is most definitely
not the case. Although, there are
circumstances when drag can be used to our
advantage, such as swinging nymphs out of a
current - a great taking zone, on the whole
drag is artificial and should be avoided at
all costs.
Often there are several solutions to
the same problem; it's always interesting to
see how different anglers cope given the same
set of circumstances - it tells you a little
about there psyche, sort of a Freud of the
river banks ("Ahh, so you did sleep with
your mother!!!" - that sort of thing).
Getting
the fly to land first: Tuck Cast
The most obvious question is not
"how?" but "why?"... well
there are two situations where I'll use this
cast:
The first is when fishing
'pocket-water'. Boulder strewn rivers
often contain so many varying
currents that they present a
bewildering puzzle. A simple solution
to give ourselves that little bit
more drag-free time is to land the
fly before the line. So long as we
can get fairly close to the pockets
(and we can often get right up behind
them) we can chuck the fly into
position and attempt to keep the line
off the water - of course the line
will land eventually, but hopefully
drag will have been delayed long
enough for the deception to have been
completed.
The second has nothing to do
with overcoming drag; rather it is
all about creating attractive 'plop'
noises. If we cast our fly to land
first it is quite easy to overpower
the stop and get a nice 'plop' sound.
Just like little bugs dropping off
branches in high summer. Also useful
for the cicada splash.
In order to get the fly to land
first, the technique used is to cast the fly
straight over the top of the rod with a
slightly overpowered overhead cast, so that
when the fly line straightens the extra
energy causes the fly to flick downwards.
There is an important refinement on this
technique; it is how we apply the extra
power: instead of stopping harder, stop the
tip normally and just as the line is
unfurling on the forward cast, lift (or pull
back) the rod tip.
Although you can shoot line with
this cast, you will have to feed the line
through your fingers so that you can stop the
line before you lift the tip.
Obviously you don't follow through
immediately with the rod tip to the surface
as this would negate all we have set out to
achieve.
