Walter & Group...
[GH] Many different answers to some of the questions. Most of you did well with them, in my opinion.
Here are some thoughts after going over all of them:
- I picked three sets of answers to send you. These, I felt, were among the best.
- Let's go over each question, briefly:
1.) Most of you preferred CASTING ARC to CASTING ANGLE.
2.) Most felt this best described the angular change in rod position during the cast.
3.) High number of correct answers, despite different wordings.
4.) In general, the opinions agreed with application of constant force resulting in acceleration.
5.) Most said that TORQUE meant a twisting force.
6.) Almost all agreed that for the most part translation and rotation occurred together during the cast.
7.) The majority said that the movement of the rod through the CASTING ANGLE (CASTING ARC) was from RSP to RSP.
8.) Most answers included a description which gave the impression that the rod bend should match the casting arc for rod tip SLP and an efficient loop.
9.) More than half said they did use some form of slide loading, though these answers included statements questioning exactly what is meant by the term.
10.) As expected, those who said they used it also saw some advantage to it. A couple of answers included a statement that while they did use it, they were not certain it really helped.
11.) Almost everybody named Joan Wulff as the first to use the term, "SLIDE LOADING".
12.) I threw this one in to see if anyone would successfully research the answer. No one did.
(Maurice ("Mooch") Abraham).
13.) Lots of differing answers on "PRE-LOAD" ! Citing a few:-
- "Rod bend derived from residual momentum in the fly line as the cast unrolls."
- "Pre-Load occurs when the unrolling fly line puts a ‘tug’ on the rod as it completes the unrolling process. This pre bends the rod without it being moved in the direction of the next stroke."
- "The rod bending due to the arresting of the momentum of the fly line by the fly rod and just prior to making the cast."
- "Don't know".
- "Initial casting movement to over come inertia".
- "A slight movement of the rod after counterflex in the opposite direction from the preceding cast before the loop has unfurled". (Three members used this same statement.)
- "Not sure".
- " The surge of the line straightening, usually after allowing some shoot, that puts a slight additional bend in the rod prior to starting the forward cast. Mainly a shooting head technique."
- "I'm not sure. I think of it as the loading of the rod before the beginning of the casting stroke. For example backward momentum of the fly line will "pull" the rod before the casting stroke."
- "I've had lots of people tell me about pre-load but whenever I've filmed them it didn't happen. Still if someone can shoot pre-load in action I'd love to see it."
- "Pre-Load occurs when the unrolling fly line puts a ‘tug’ on the rod as it completes the unrolling process. This pre bends the rod without it being move in the direction of the next stroke."
14.) Most doubted that we really have PRE-LOAD on most of our fishing casts. Two said we have it on all casts.
15.) To the question:" Under what circumstances, if ever, is a caster likely to achieve pre-load?", the answers ranged from those who said it never really occurred through those who opined that it usually occurred on to some who said it always occurred:
- "Doubt it."
- "Most people who cast nice dynamic loops will always have preload to some extent."
- "Can not cast without pre-load."
- "When deliberately trying to capture momentum from a back cast to enhance the following forward cast. Whether momentum in the opposite direction would enhance any cast is, for me, questionable.
16.) On the favored definition (description) of CASTING STROKE, we had no two answers the same. This is a reflection on the fact that we really don't have an agreed upon definition. Some responses:
- "Rod movement to form a loop"
- "I define the casting stroke as the total motion of the hand from the beginning to the end of the cast. I think drifting and follow through are part of the stroke."
- "Movements of the fly rod butt from the beginning of the cast to the stop."
- "I demonstrate what a loop made by the fly line looks like and explain that the fly line delivers the fly to the target and then demonstrate how to move the rod to get the loop. Then tell them we call this a casting stroke."
- "repositioning of the rod and subsequently the line to deliver a fly to a target."
- "The movement of the rod over a certain distance that moves the line to deliver a fly to a target."
- "The casting stroke begins with the first rod hand movement in the
direction of the cast and ends when the caster stops the rod butt or
releases his grip on the line."
- "From the time the rod starts to move in one direction until it stops moving in the opposite direction. This would include both rotation and translation."
- "Any that allow for the stroke to be fluid (contiguous)."
- "CASTING STROKE is the total movement of the fly rod made to as part of the cast. It consists of rotation and translation."
- "Movement of the hand leading to loop formation."
17.) Many different answers to the question: "BRIEFLY: What do you tell your students about the CASTING STROKE?
- "A cast is an acceleration to a stop."
- "I tell beginners that the movements they make with the fly rod to propel the fly line in one direction is the casting stroke."
- "I tell the students they need to relate their casting stroke to the resulting cast and line layout. They are in control of their cast through the casting stroke."
- "That the casting stroke is used to accelerate the line and an abrupt stop of the hand in the appropriate place will create the loop that will deliver the fly to the fish."
- " I tell them the casting stroke begins when the end of the fly line (i.e. fly) starts to move and ends when the line straightens in the opposite direction. With more advanced students I'll get into translation and rotation."
- "Short cast, short stroke. Longer cast, longer stroke."
- "The casting stroke should be made with little noise and in a straight line as possible."
- "It is made up of a casting and stroke length or translation."
- "16./17. I demonstrate what a loop made by the fly line looks like and explain that the fly line delivers the fly to the target and then demonstrate how to move the rod to get the loop. Then tell them we call this a casting stroke."
- "Smoother, Shorter, Longer, Faster at the End, Slower at the Beginning, On Plane, Thumbnail Path, Add Arc, etc."
-"Movement of the hand in the direction of the cast."
18.) All said that the path taken by the casting hand was not in a straight line when SLP of the rod tip was achieved.... except three.
19.) Most said that you can't load a fly rod without acceleration.... but several qualified that by saying that as the cast was begun that some acceleration had to occur. Examples:
- "I can't move it without acceleration".
- "No. Remember a fly line has very little mass (which is 1/32nd of its weight). What you feel as “weight” of the line is the acceleration. The faster you go (accelerate) the more resistance you feel."
- "No."
- "I don't believe so. Moving a stationary fly rod requires acceleration."
- "You can't move the rod through a casting angle without applying a force no matter how slight, and a slight force will probably induce a slight bend."
- "Yes, the weight of the line will cause some bend/load in the rod, probably not enough to make a cast."
- "Not to the extent required for a fly cast. If a cast is started with a
bend in it the rod will begin un-bending unless force is applied
throughout the casting angle. If force is applied throughout the cast the
rod will accelerate. If the rod does NOT accelerate, then the force has
been removed and the rod will unload."
20.) Most said that the haul was important when hand casting. Several pointed out that the casting arm functions as a lever which traverses a casting arc.
21.) 22.) Almost everyone got those right. Some pointed out that when insufficient force to develop enough rod bend for the amount of the casting angle (arc) occurred that the cast might collapse. This would depend upon the amount of line involved, the resistance, and the amount of force actually applied.
23.) Almost everyone agreed that they did perform the exercises in 21.) and 22.) as a demo. for their students.
24.) Almost all picked "d" (MCP) as the first time the rod tip stopped.
25.) Lots of different answers on DRAG:
- "My understanding of drag (as opposed to “Slide”) is a translational
rod/body re-positioning move occurRing when the line is clamped and the rod
and line rod leg both move in the same direction at the same speed. It
usually occurs after a bit of “slide” and can help to extend the amount of
available haul length for some casting styles. There is a video somewhere
I saw of a man named “Nelson’ something in Europe casting using almost
pure “drag” as I recall. Perhaps one of the group knows it. Very good
video - in slow motion too. I can’t find it."
"A little or no angular change translation of the rod prior to rotation proper."
- "DRAG, I hate that term. To me it connotes a crude or uncontrolled movement. I prefer DRAW. By whatever name it is a motion in the beginning of the stroke predominated by translation. In this stroke initial movement is provided by the direct motion of the body and arm. The multiplicative effect of rotating the rod is saved until the later portion of the cast when it is needed to keep up with the speed which has been generated by the earlier portion of the stroke."
- "For me, drag is simultaneous translation of rod and line hands, usually with the rod essentially horizontal, immediately prior to commencement of rotation in a casting stroke. "Slide loading" without the slide."
- "Drag is the translation movement of the rod in the direction of the casting stroke. In a perfect world drag does not take away from the available casting angle."
- "Translating without acceleration."
- "Loaded question! Are we talking about the resistance of air and or water against the line when starting a cast? Or perhaps the drag created by the guides when shooting line. Then there is the drag created by moving water against the fly line, which we compensate for by mending to allow a drag free float of the fly. When fighting a fish we have the drag of the reel, drag created by palming the reel or pulling the line into the grip of the rod and of course the drag of the line against the water as the fish moves to make its escape."
- "Rod translation during the early part of the casting stroke to establish momentum."
- "Not sure if there is drag in casting.
- One simply sent a PowerPoint picture sequence of Rick Hartman's cast starting with lots of drag ! (I included the pictures in an attachment.)

[GH] I've spent a great deal of time going over all of your answer messages. Two things stand out. 1. The agreement on many issues. 2. Vast differences of opinion on things like CASTING STROKE, "PRE-LOAD", DRAG, and SLIDE LOADING.
I'm particularly concerned about the apparent differences of opinion on the widely used term, CASTING STROKE. Makes me wonder if we really have a handle on this. Particularly troublesome when we see our answers in the light of Bruce Richard's article in the latest edition of the LOOP ! *
Our FFF has yet to come up with an approved list of definitions.
Compare some of these answers with your own. Try to come to your own conclusions.
