From Jeff Wagner:
Great comments! I find myself thinking more like Mac with
every
post!
I don't remember all of the uses (of the
continuous
tension/belgian/elliptical)
mentioned so far, but will give my
main uses.
Fishing nymph rigs, double streamer rigs, and really any
double
fly rig. To
keep them separated while casting it often makes
it easier to
use an
elliptical
cast. It is also easier on the
connecting knots than a instant
change of
direction.
To take this
another step with clients using a short line this
cast becomes
essential
as any over head casting almost certainly ends up in
disaster.
I
will offer this cast and variations (as Mac mentioned) above
horizontal
to
ticking the waters surface. Line management is easier, there
is
no wrist-dump
behind the caster and they have an easier and longer
time
visualizing the line
as it moves to the side instead of
overhead.
What, too much emphasis on distance!!! lol I would have
to
(hesitantly) agree
(as I prepare for distance demos at the upcoming ISE
shows!).
It is important
to pursue mastery of the many facets of
casting!

I strongly recommend you access and study the article by Jim Valle on preparing for the MCCI exam in the last issue of the LOOP.

From Steve Hollensed:-
Hi Gordy,
I would like to add my 2 cents on WHY constant acceleration is
important. I believe it relates to one of our casting essentials, that
of a SLP of the rod tip.
Really, there is only one thing that will load or bend the rod in the
end, and that is a net force. Forces are produced by accelerating a
mass, in this case the fly line. (F=ma)
If we apply constant forces, then the rod will be bent in the same
amount through out the casting stroke ( the portion of the stroke under
load). This is achieved via constant acceleration. Varying the amounts
of acceleration will produce varying amounts of force which will in turn
cause the rod to load and unload during the stroke creating departure of
SLP.
In my estimation, this is why it is good to load the rod with smooth,
constant acceleration.
It is also important here to understand very well the difference between
velocity and acceleration. High velocities are required at the end of
the stroke just to maintain constant acceleration, thus constant forces.
As Troy point out so eloquently, if you reduce the velocity, you reduce
the force acting on the tip by reducing the acceleration and the rod
begins to unload resulting in loop formation.
I think this is seen in the Analyzer graphs. The good casts have a semi
straight line in the casting stroke on the tip speed versus time curves.
This indicates constant rate of change in the tip speed, or constant
acceleration.
This is also seen with beginners not loading the rod. Constant speed
does not produce a force to load the rod. No change in speed - no force
- no rod loading.
Just some thoughts, that I hope relate cause and effect.

Makes good sense, to me.

From Troy Miller:
In response to the Belgian cast issue (and again I want to say, I don’t know if I’m doing a “proper” Belgian cast), I’m nearly certain that my rod tip NEVER stops motion at any time during the strokes – up to final presentation delivery. The low slung backcast transitions pretty smoothly as I’m changing planes and then I “power on” going forward when the time is right. Done this way, there are ALWAYS accelerations. Some are positive, some are negative, but there’s no significant period where I’m at zero velocity or acceleration. That’s how I maintain continuous tension between the rod tip and the flyline.
Wish I had a flyrod up here to check it out more thoroughly. Anyone know how a flyline behaves at -40 degF? Bruce? J

That is what I meant when I said that I could do the, "Belgian cast" (or a variation of it) with no defined stop. I don't know that there is a correct way of doing it, ie. with a stop, then change of rod planes or with continuous tension and no true stop.
