    Hi Gordy
     
    My response to the "casting mechanics" quiz  

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    QUESTIONS:

    1.)  Give us your description of DRIFT.  On completion of the casting stroke, an intended re-positioning of the rod in the direction of the unrolling loop.  

    Yes.  Note that I asked for "your description" .... NOT a formal definition.  Different groups of instructors will have different definitions.  One oft used is :  DRIFT:  MOVEMENT OF THE FLY ROD WHICH INCREASES AVAILABLE STROKE LENGTH AND CASTING ARC.    Some look at it differently when describing elliptical casts such as Spey casts.    G.

    2.)   What (if anything) can it accomplish ?  Provides space for more stroke length and subsequent tip travel if needed for the upcoming cast. 

    -Can help to set up the trajectory for the following cast.

    -Can provide pre-load of the rod throught the momentum of the unrolling loop bending the rod. 

    -Useful instruction technique for deterring "creep"   

    Agree.    G.

    3.)   When, during the casting stroke, is the rod tip moving at its fastest rate ? At the rod straight position.  

    Yes.... or perhaps a nanosecond prior to RSP.      G.

    4.)   At what point do you think loop formation begins ? According to Bruce and the analyzer it's at  .1 second after RSP.  For all intents and purposes I would tell a student that the loop begins to form when the rod tip has stopped accelerating and the following fly line begins to overtake it. 

    That is probably correct, though even the fastest video I've studied (500 fps.) didn't prove for sure that it wasn't AT RSP.  Might be a tiny bit prior or after.  When we study this with super fast video of above 1000 fps we'll come closer to really knowing.

    I belive Bruce actually found that the rod tip was moving fastest between the caster's rapid deceleration (stop) and RSP and that that time interval was about 0.1 second.       G.

       

    5.)   What is your idea of the meaning of the term, CREEP ? A slow unintentional movement of the rod in the opposite direction of the unrolling loop

    OK.  Again, I didn't ask for a formal definition, because I know there is not consensus on one.  One working definition is:  CREEP:  MOVEMENT OF THE ROD WHICH DECREASES AVAILABLE STROKE LENGTH AND CASTING ARC.

    For those who place CREEP within the  CASTING STROKE,  and in view of the discovery that CREEP is almost always rotational, a working definition would be:  CREEP: MOVEMENT OF THE ROD WHICH DECREASES AVAILABLE CASTING ARC.    G.

    6.)   Do you think CREEP is always a fault ?  Yes

    Statement of opinion ... so no right or wrong answer here.  Most instructors would agree with you.  Some exceptions :

    1. The caster purposely makes an out of plane tail to flip a fly beneath overhanging brush  (So called, Maloney Cast.)

    2. The caster uses a CREEP move the purposely shorten his stroke and casting arc as he false casts and realizes that he has more line out of his rod tip than needed as he suddenly feels the need for a shorter cast.  Of course this is not a good "fix" as he'll have to make a lot of other changes at the same time to avoid a tail.   CONTROVERSIAL AT BEST.    G.

    7.)   What happens when a caster creeps ?  Usually a tailing loop.  An explanation would include that creep shortens the available casting stroke resulting in a improper application of power resulting in a concave tip path and subsequent tailing loop.

    Yes.    G.

    8.)  You have taken a high speed video of you friend's forward cast.  You picked out one frame which showed the point of maximum load.  How did you pick out that particular frame ?  Don't have a high speed video camera, but I would compare each frame to the other to find the frame that showed the greatest rod bend in the whole sequence.

    Agree.      G.

    9.)  When (if ever) would you purposely cast with different timing of the forward cast from that of the back cast.  In a tail wind or head wind situation.

    -After shooting line into a back cast

    -When demonstrating timing as a casting faul

    Agree.     G.

       

    10.)  You just made a forward cast .... but you didn't stop.  Rather, you simply slowed your rod.

               a. Will your rod unload anyway ? If it was bent during the cast, then it has to unbend eventually.  I would say Yes.

    Agree.    G. 

               b. Was it possible to form a loop ? Could it be described as "non loop"? 

    You can form a loop.  It won't be a tight/small one because the rapid deceleration we call the stop has as one of its valuable functions the ability to control the position of the rod tip as the fly line overtakes it as the loop forms at or near RSP.   If the caster slows the rod over a greater time interval, an open "non-loop" may result.      G.

    11.)  What is meant by the term COUNTERFLEX ? The direction the rod bends after RSP

    Yes.    G.

    12.)  Is it the same thing as REBOUND ? No, Rebound is the direction the rod bends after counterflex.

    Agree.   G.

    13.)  You just made a high trajectory back cast.  Using exactly the same rod plane, you made a forward cast with trajectory parallel to the water.  What happened to the loop ? It probably formed a tailing loop, because the casts were made in different line planes.  

    Casting in different line planes (trajectories) won't result in a tailing loop UNLESS THERE IS LESS THAN 180 DEGREES BETWEEN THE TRAJECTORIES OF THE BACK CAST AND THE FORWARD CAST.   G. 

    14.)  Your casting stroke and casting arc are too short for the amount of line carried out of the rod tip.  Describe the resulting loop. A tailing loop probably formed.  Because the stroke length did not match the line length, proper power  application could not be maintained resulting in a concave tip path.    

    Agree.  One prime way to form a tail.  The stroke length and casting arc must match the bend of the rod and the amount of line carried for efficient casting and the avoidance of a tail.      G. 

    15.)  You purposely made a forward cast with increased casting arc and resulting convex path of the rod tip at the beginning of your stroke, then accomplished an almost straight line path of the rod tip until the conclusion of your stroke as you unloaded the rod with the rod tip a short distance from the oncoming line.

               a. What happens to your loop ?The fly leg would be high and the rod leg would be straight.   Agree    G.

               b. When (if ever) would you do that ? Might be useful for a "wind assist" cast.  Also for demonstrating controlled loop shapes.   Yes.     G.

    16.)  At another time and under different conditions, you made a cast with an almost straight line path of the rod tip until the end of your stroke at which point you applied enough convexity of your rod tip path to unload the rod with the tip well below the oncoming line.

               a.  What loop resulted ?  Straight fly leg and rod leg lower and with a more open loop.  Agree.     G.

               b.  When, (if ever) would you do that ?  When casting controlled loops with heavy weighted flies, sink tips, etc.

    Yes.     G.

     17.)  What is likely to happen if you apply a spike of power to your haul very early in the stroke ?  A tailing loop will form.    Agree.   G.   

    18.)  Why ? The rod tip is forced  to travel below a straight line path causing the tailing loop.

    That spike of haul power will result in increased acceleration which cannot be maintained throughout the stroke.  The rod tip dips down as rod load increases, then rises as the load decreases ..... a concave rod tip path.     G.

    19.)  Your new casting student asks your advice on what rod to purchase for his lessons.  He's been told about fast action, medium action, and slow action rods.  What do you advise him ?  His best bet would be a medium action rod.

    Agree.    G.

    20.)  Give your reason (s) for this decision. A fast action rod may require more precise casting stroke movements than a beginner can handle. Rod load may not be experienced by an inexperienced caster and lead to more open loops.

    Yes.  Also, with a very fast action rod everything happens so fast it is hard for the student to grasp what is going on.    G.

    A slow action rod casts best with a slow smooth power application that may not be the best choice for a beginner.  It is more prone to over load and cause tailing loops.  

    Yes.     G.

    Well done, Doug !          Gordy

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    From Jerry Puckett.  A few comments in his text in italics       G. :

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    QUESTIONS:
    1.)  Give us your description of DRIFT.
     
    Same as follow through on the forward stroke--extension of the rod after the stop.
     
    Many would agree with you.  I favor this concept:
     
    I look at DRIFT , when straight line overhead casting, as movement of the fly rod which increases available stroke length and casting arc (for the next cast).  So ... when false casting, I see DRIFT as used (if elected) after the back cast and after the forward cast.
     
                                                                      except:
     
    When done after the delivery cast..... since there is no next cast.  On the delivery cast, I call it FOLLOWTHROUGH.    G.
     
    2.)   What (if anything) can it accomplish ?
     
    lengthen the stroke for the next cast, also helps prevent creep
     
    Agree.  I'm glad you said "helps prevent..."  In a way, DRIFT can be seen as the antithesis of CREEP.  Many instructures use it as the "cure" for unwanted creep.
     
    All this despite the fact that one can make a back drift and then creep.  Unusual, but possible.       G.
     
    3.)   When, during the casting stroke, is the rod tip moving at its fastest rate ?
     
    Rod Straight Position      Yes...   or so close that we cannot be certain within a frog hair or so      G.
     
    4.)   At what point do you think loop formation begins ?
     
    When the line passes the rod tip.    Yes.   When it starts to pass the rod tip.    G.
     
    5.)   What is your idea of the meaning of the term, CREEP ?
     
    Starting the casting stroke before the line has completely unfurled   
     
    Well.... I'd see that as premature application of power.   I look at CREEP as minimally accelerated (zero to slow) movement of the fly rod, usually unintended, in the direction opposite that of an unrolling loop (or newly unrolled loop) which diminishes available stroke length and casting arc for the following cast.    G.
     
    6.)   Do you think CREEP is always a fault ?
     
    Yes, always shortens the available casting stroke
     
    Valid opinion.  (Some feel that there might be a time when it could be used to purposely shorten the casting stroke and casting arc. )   
     
    CREEP can occur on either on the forward cast or the back cast.  When it occurs at the start of the back cast, I like to call it "reverse creep"     G.
     
     
    7.)   What happens when a caster creeps ?
     
    Most likely a tailing loop       Usually so ... because the caster senses the lack of ability to likely make the distance and uses inappropriate application of power leading to a concave rod tip path and a tail.    G.
     
    8.)  You have taken a high speed video of you friend's forward cast.  You picked out one frame which showed the point of maximum load.  How did you pick out that particular frame ?
     
    Where the rod has its deepest bend.     Agree.    G.
     
    9.)  When (if ever) would you purposely cast with different timing of the forward cast from that of the back cast.
     
    When casting into a wind--headwind or tailwind.      Yes.    G.
     
    10.)  You just made a forward cast .... but you didn't stop.  Rather, you simply slowed your rod.
               a. Will your rod unload anyway ?
                   Yes
               b. Was it possible to form a loop ?
                   yes
     
    Agree.    G.
     
    11.)  What is meant by the term COUNTER FLEX ?
     
           Movement of the rod in the same direction after the stop.
     
    More accurately, AFTER RSP.    G.
     
    12.)  Is it the same thing as REBOUND ?
           
           No, rebound is in the opposite direction of counter flex.     Yes.   G.
     
    13.)  You just made a high trajectory back cast.  Using exactly the same rod plane, you made a forward cast with trajectory parallel to the water.  What happened to the loop ?
     
    Not sure I understand this one--but I think a tailing loop is possible. 
     
    Correct.   Any time the caster makes a back cast and then a forward cast with less than 180 degrees of trajectory (line plane) between them AND THE ROD PLANE IS NOT CHANGED, a tailing loop is possible.  One might look at it this way :   There is a concavity between strokes.     G.
     
    14.)  Your casting stroke and casting arc are too short for the amount of line carried out of the rod tip.  Describe the resulting loop.
     
    Tailing loop    Yes.    G.
     
    15.)  You purposely made a forward cast with increased casting arc and resulting convex path of the rod tip at the beginning of your stroke, then accomplished an almost straight line path of the rod tip until the conclusion of your stroke as you unloaded the rod with the rod tip a short distance from the oncoming line.
     
               a. What happens to your loop ?
     
                  A wide loop narrowing to a tighter loop
     
    Check Doug's answer.  He was right.   This yields a wide loop with the fly leg way up and the rod leg fairly straight.  Can be used to "kite" a fly when casting with wind from behind.   G.
     
               b. When (if ever) would you do that ?
     
                   Tail wind for kiting purposes     Yes.     G.
     
     
    16.)  At another time and under different conditions, you made a cast with an almost straight line path of the rod tip until the end of your stroke at which point you applied enough convexity of your rod tip path to unload the rod with the tip well below the oncoming line.
     
               a.  What loop resulted ?
     
                    An open loop
     
    If done to extreme, that might happen.  When performed moderately, it can yield a well controlled large enough loop for use with weighted flies.    G.
     
               b.  When, (if ever) would you do that ?
                 
                    Casting heavy flies      Yes.    G.
     
    17.)  What is likely to happen if you apply a spike of power to your haul very early in the stroke ?
     
                  Tailing loop      Yes.    G.
     
    18.)  Why ?
     
                  Creates a concave path of the rod tip.      Yes.    G.
     
     
    19.)  Your new casting student asks your advice on what rod to purchase for his lessons.  He's been told about fast action, medium action, and slow action rods.  What do you advise him ?
     
                  Medium action rod    Agree.   G.
     
    20.)  Give your reason (s) for this decision.
     
    Able to feel the rod load with less effort compared to a stiff rod (less likely for injury).  A slower rod makes timing more difficult.
     
    True.   Check out my comments to Doug's answer.    G.

    One more set of answers from Maryann Townsend :
     

    I?ll give it a stab. . .


    QUESTIONS:

    1.)  Give us your description of DRIFT. After the stop the rod hand continues or stretches or drifts a little further back.

    2.)   What (if anything) can it accomplish ?  A longer casting stroke

    3.)   When, during the casting stroke, is the rod tip moving at its fastest rate ?  Between the stop of the casters hand and when the rod straightens out.

    4.)   At what point do you think loop formation begins ?  When the rod straightens or unloads.

    5.)   What is your idea of the meaning of the term, CREEP ?  It is better to be a drifter rather than a creeper. Someone once told me that.  The students rod hand is creeping forward after the stop ? prior to the cast.

    6.)   Do you think CREEP is always a fault ?  Yes

    7.)   What happens when a caster creeps ?  Creep is a bad thing ? it us usually done when the caster tries to prep for the continuation of the cast after the stop.  Rather than keeping the hand still after the stop or drifting after the stop to extend the cast the caster will allow the casing hand to creep forward then make the cast ? resulting in a shorter less efficient stroke and more than likely a tailing loop.

     8.)  You have taken a high speed video of you friend's forward cast.  You picked out one frame which showed the point of maximum load.  How did you pick out that particular frame ?    The rod is at its deepest bend.

    9.)  When (if ever) would you purposely cast with different timing of the forward cast from that of the back cast.  Changing directions and Wind may play a role here.

    10.)  You just made a forward cast .... but you didn't stop.  Rather, you simply slowed your rod.

               a. Will your rod unload anyway ?  yes to some extent - but not with much efficiency

               b. Was it possible to form a loop ?  yes it is possible? but a very wide loop

    11.)  What is meant by the term COUNTERFLEX ?   It is the immediate bend of the rod just after the rod comes to the straight position

    12.)  Is it the same thing as REBOUND ?  No. The rebound occurs just after the counterflex.

    13.)  You just made a high trajectory back cast.  Using exactly the same rod plane, you made a forward cast with trajectory parallel to the water.  What happened to the loop ?  Hmm ? If I understand the question . . . this is the cast   \ _    the caster has changed the 180` trajectory and will most likely result in a concave path of the rod tip and tailing loop.

    14.)  Your casting stroke and casting arc are too short for the amount of line carried out of the rod tip.  Describe the resulting loop.  This will cause a concave path of the rod tip forming a tailing loop. There is too much bend or load in the rod in a cast that is too small.  The 180` casting concept should be further explained to the student.

    15.)  You purposely made a forward cast with increased casting arc and resulting convex path of the rod tip at the beginning of your stroke, then accomplished an almost straight line path of the rod tip until the conclusion of your stroke as you unloaded the rod with the rod tip a short distance from the oncoming line.

               a. What happens to your loop ?  First loop, backcast, is large almost a non-loop ? forward cast must try to compensate for the wide/non-loop and try to pull the line thru to the target.

               b. When (if ever) would you do that ?  Casting big bass bugs ? picking up slack on the water/ground

    16.) *  At another time and under different conditions, you made a cast with an almost straight line path of the rod tip until the end of your stroke at which point you applied enough convexity of your rod tip path to unload the rod with the tip well below the oncoming line.

               a.  What loop resulted ?   Wider loop at the end of the backcast

               b.  When, (if ever) would you do that ?  Windy conditions to help straighten the line

    17.)  What is likely to happen if you apply a spike of power to your haul very early in the stroke ?  Concave path of the rod tip ? tailing loop.

    18.)  Why ?  A ?spike? of power will cause the rod tip to dip below the straight line path of the rod tip.  (I know ? I used to do thisJ)

    19.)  Your new casting student asks your advice on what rod to purchase for his lessons.  He's been told about fast action, medium action, and slow action rods.  What do you advise him ?  I would advise a medium action rod.

    20.)  Give your reason (s) for this decision.

    A fast rod is just that ? ?FAST? everything happens fast ? it is sometimes very difficult for the student to feel or even for that matter to see what is happening during the cast.  Timing is everything if they can?t get a feel for the timing ? it is time to switch rods ? at least for a short time ? I always make sure I have a couple extra rods of various size and speed in my truck for emergencies or for just this reason.

    A slow rod I find can also be difficult for a new caster ? can you feel the rod load/bend ?YES? but it is just the opposite of the Fast rod ? timing can be very difficult to master for the beginning caster.
