[GH] From Rick Brown :
Gordy, concerning, Nature of Fly Casting. All the books remaining were sent to Amazon last September.

[GH] Rick,
I didn't know that. Thanks.
In past years, I've found that sometimes the author will retain a few. Jason's father, Gary Borger did that.
For long out of print fly casting books, it's hard to beat help from a professional like Bob Rumpf who's primary expertise is that field.

[GH] From Phil Gay :
Gordy,
An Interesting thread indeed!
I like Gary's use of the term pace. I often use it myself when someone is starting forward so slowly that they get force to over apply power in the remaining stroke. I advise the student to start forward with a little more pace/speed.

[GH] Phil,
Yes ... like, "Pick up the pace" or: "Put some authority into your cast ".

[GH] From Ally Gowans :
Hi Gordy,
My reason for using acceleration of the rod tip is twofold, firstly it removes any statement of force and its neural association with strength (of course force and acceleration are inextricably bound), and it defines where the associated force is applied i.e. at the rod tip where it is not unreasonable to consider that the motion is intended to be more or less straight.
If what happens at the rod handle is considered the use of the word force I suggest is not only tends to create the wrong impression to students it is incorrect if any torque is involved so we to be correct would have to say “incorrectly applied force and or torque” since some casts employ mostly torque to drive the rod tip.
Now, how many students understand torque and moment of inertia?
How many might know the much easier to understand relationship between force and acceleration (F=ma) which given a constant mass demonstrates that the application of force by the rod tip produces a proportional acceleration whilst the rod tip is pulling the line forward. This is not something that the instructor can assume! For students you can therefore redefine acceleration as taking place whilst the rod tip is pulling line in the direction of the cast and if they do that smoothly there will be no problems with tailing loops.
This may not be helpful to all instructors but I have not come across a student who didn’t understand how to make smooth casts by explaining it thus because they can feel the rod tip smoothly pulling the line and that “feel” is hugely important in good fly casting.
Best regards,
Ally Gowans

[GH] Ally,
I have found that many students respond well to terms like "pull" rather than "push" as well as the words "smooth" and "smoothly". Some don't respond well if at all to terms like "constant acceleration".
When casters push the rod forward, they usually also diminish the the casting arc and end up not dipping the tip of the rod out of the way of the oncoming line. Acceleration and torque are insufficient as well. Another complex scenario which can yield tails by means of the same things we've already discussed.
In reviewing Paul Arden's description of his way of teaching the pickup-and-laydown, I an see that this begins to teach the concepts of "pull" and "smooth acceleration" very early in the game. Both lead to diminished likelihood of tailing loops. For those and other reasons, I know Paul has suggested adding the PU&LD to the exam. *
* Pick up and Lay down.
