Hi Gordy,
In regard to the discussion of overpowered curve casts, here are some
observations I have had.
When I make a overpowered curve cast and do nothing more than good hard stop
at the end of the stroke, I will essentially get a hook where the leader and
maybe a couple of feet of the fly line hooks to the left (right handed cast).
However, if I make the stop and keep a tight grip on the rod with an additional
amount of pressure from the heal of my hand on the rod grip, I will get the
curve much farther up the fly line. Keep in mind that I don't try to pull the
rod tip back. I just try to reduce the amount of damping as much as possible
(for a large curve). I had always thought that this move does two things: 1)
makes turnover faster, therefore creating more kick to the fly. 2) increase
rebound of the rod tip to have the rod throw a "mend" in the rod leg of the
line. I also have found that by varying my "death grip" on the rod after the
stop I can somewhat adjust the size and length of the curve.

Eric....
The greater the negative acceleration ("harder you stop") at the end of your
overpowered curve cast, the greater the counterflex and rebound. The
former helps place the fly in the direction you sent it as your rod tip came to
RSP, and the latter assists by increasing the depth of the curve.
This is a true overpowered curve cast.
When I go one step further and make a move opposite the direction taken by
the fly after the cast, I'm assisting rebound. By adding to it, I can
increase the depth of the curve and / or sharpen it into a 90 degree hook,
depending upon my timing of this move. In any event, when I use this
method, I end up with one of two things:
1. A, curve
cast/mend. 2.
A, hook cast/mend.
This based on a useful definition of the term, MEND to mean repositioning the
fly line after the cast.

From Walter Simberski :-
Gordy - In one of the classes I had with Jason
Borger at a past conclave he pointed out that the stop can be difficult to
actually see, especially when
beginners are watching an advanced caster. The
problem is that an advanced caster will execute a stop and then continue
smoothly into the drift such that
the beginner thinks they are seeing a casting arc
of nearly 180 degrees. I believe this is one of the reasons Jason uses the terms
ALE and ATE to describe
the basic stroke. Jason's terminology also fits
well when watching Paul Arden's distance cast. As you know Paul's casting arc
actually is about 170 degrees and many people describe this as a stopless cast
because he makes no effort to rapidly decelerate the butt of the rod at any time
during the
casting stroke. The rod butt naturally coasts to a
stop after the rod has unloaded whic result in some people calling it a slow
stop . If you watch Paul's casts
in slow motion you can see that there is a
point in the cast where the rod goes from
maximum load to rsp very quickly - there are a number of reasons that
come together to create this unloading point
(even though the caster has done nothing to
specifically cause the rod to unload, i.e. decelerating the rod
through the use of his muscles). One of the
major contributing factors is that the rod tip is
moving in an extremely flattened elliptical path. As the rod tip
nears the pointy end of the ellipse the application
of force on the rod tip transitions from forward to downward very quickly. Other
contributing factors are the
fact that, even though the rotation is continued,
the caster has "run out of arm" and is unable to continue applying force in the
forward direction; also the changing angle of the rod butt to the line plane
reduces the amount of resistance from the line on the rod. All of these things
are timed to occur together
resulting in the rod going from maximum bend to rsp
very quickly and to ensure that energy is transferred from the rod to the line
very effectively, i.e. in
the direction of the cast.
Another confusing thing is watching a caster like
Steve Rajeff who applies a thrusting motion at the end of his stroke that,
again, makes it appear to a
beginner that the
casting stroke is nearly 180 degrees.
When I'm working with beginners I like to introduce
the idea of drift very soon after they have learned the basic casting stroke and
explain that the stop
has to occur at the same place but then the rod is
repositioned to allow for a longer stroke which can be used for a more relaxed
casting stroke or
to allow additional application of power for a
longer cast. I then make sure they understand that the rod still has to unload
in the same place, and that
this requires a deceleration of the rod at this
point.
Thanks for listening
Walter

Walter.... I think Jason is absolutely correct. I also think your
analysis is right on target. (More fun to find something to challenge, but
I can't.)
