Walter & Group....
From Peter Lami :
Gordy,
The question before the Master Study Group is "What is your concept of
variables?" Bill Gammel came closest to formulating a set of rules to
help guide us in this matter with his famous Five Essentials [sic].
- During the casting stroke, the rod tip must travel in a straight
line path.
- The casting arc, or angle at the rod butt, must vary in width with
the amount of line beyond the rod tip.
- There must be a pause at the end of each stroke.
- The application of power must occur in the proper amount at the
proper place in the stroke.
- No slack line can occur during the casting stroke.
These rules are the FFF generally accepted exemplar of a basic straight
overhead cast. These rules can also be applied to all elliptical cast if
you are willing to accept that RULE #1 is a variable, i.e. the rod tip follows
an elliptical path, and that the rod plane is a variable too. It makes
good sense to expand Gammel's rules and accept the possibility that RULE #1 is a
variable too in a bigger picture sense. To become a FFF Master certified
fly casting instructor you must learn how to teach all the elliptical casts and
Spey casts to students. I submit to you, that this is a deeper level of
knowledge and understanding which separates CCI's from MCCI's.
Again, "RULE #1 is the rod tip must follow in a straight line path.
Your student will make a perfect cast every time if he/she can achieve
RULE #1. Of course, this is easier said than done because of all the
variables in fly casting which are well known to the Master Study Group
community. RULE #2, #3, and #4 are variables, to which we can add such
things as how much the student bends his/her wrist, other body movements of the
caster, acceleration, the stopping sequence starting at maximum rod load and
ending at rod straight position, rod plane, windy weather conditions, or an
unstable casting platform such as the bow of a salt water flats boat, ad
nauseam.
Dusty Sprague, FFF Fly Casting Board of Governors, doesn't like to use any
of the basic premises put forth by Gammel's advocates when he teaches.
It's worth recalling what Dusty said:
"Several years ago I searched for a term to describe the variable elements
of casting. I was not totally comfortable with the 5 essentials; they are
good but did not fit with the way I wanted to describe casting to my
students. I settled on 'principles' and 'variables' and teach the
following:
- 3 Principles of Casting - must be executed for every cast - they don't
change - remove slack; load and unload the rod; and the cast goes in the
direction the tip finishes....
- 5 Variables: Power (hand speed/rod bend), arc, stroke length,
timing, and trajectory - all varying with the amount of line/weight to be
cast.
There is a lot more description and explanation behind each one of the
above....but you get the idea."
I couldn't agree more with Dusty. In my experience teaching, the
crucial variable that that students find most mysterious is acceleration, and
the proportional loading of the rod, that must be learned as a skill in order to
achieve RULE #1. It's not that difficult to teach students if you stop
saying "Power" and start using the term "Acceleration" because the term power is
too synonymous with strength and muscle. I always begin with a definition.
Acceleration is the change in velocity over time. All students
instinctively know how Newtonian physics work. For example, when we
accelerate an automobile we can feel being pressed into the driver's seat and
the arc in our backbone changing. The faster you accelerate the movement
of your rod hand, the more the rod will bend. Then I add this simple
instruction. Start slow and end fast when you accelerate. Finally, I
sum it all up for the student and explain that by perfectly matching
acceleration (stroke speed) with the casting arc (rod arc), we are able to
achieve RULE #1.
Fly casting is a very difficult skill to teach students and that should not
come as a surprise now that the Master Study Group has examined all of the variables. The difference in
skill levels between beginner and expert is the ability to control all of these
variables. I am always impressed watching an expert caster...it all seems
so effortlessly. It just proves again how instinct fly casting skills
really are. It just take practice.
Gordy Hill and Carl Zarelli really uncovered a gem with this topic of
discussion. A question like "What is your concept of variables?" on your
Master oral examination could be a critical pass/fail moment for a candidate and
I can think of others. For example, "How would you change Gammel's 5
Essentials?" Do you see the connection between these two questions?
Enjoy the journey. :-)

Peter....
Your message represents some deep thinking
!
I daresay that Jay and Bill Gammel were indeed
thinking of straight line overhead casting when they wrote about the
"essentials." Are they still "essentials" as we apply changes to
them as variables ? Is a straight line path of the rod tip an "essential"
when making a controlled wide loop cast when casting a heavy weighted fly
? If we have an absolutely straight line path of the rod tip throughout
the entire cast can we avoid a collision ? Will not a slight VARIATION of
this path with a bit of tip path convexity prevent this ? Perhaps, in as
much as we may see variables as modifications of the "essentials" to suit a
purpose.
Since this is a discussion of individual's
concepts of the Variables, I didn't intend that there would be any
"right" or "wrong" answers.
If you look back on the entries which
followed our question, you will note that those whom you will recognize as
Masters and well informed teachers gave logical answers though no two were the
same.
I think you are correct in looking
at our question as a good one for a Master oral exam..... not
that we would expect any kind of "pat", "memorized" or "canned" answer.
Far from it. Evaluating the candidate's way of handling this question,
however, would go a long way in helping us evaluate his/her in-depth knowledge
of fly casting as well as handling issues for which we do not have final answers
and therefore fall into the catagory of concepts.
