Walter & Group...
[GH] interesting question from Paul Bartlam :
Gordy
I am new to the group so maybe I have missed this;
has anyone explored tail placement as a function of tail wave velocity versus loop velocity?
For example a powerful tail wave early in the stroke may be able to catch the casting loop formation soon in the stroke. Therefore, showing up early in the stroke.
Whereas a non-powerful tail wave formed at the same early place in the casting stroke would follow behind the casting loop at a slower rate that allows the tail to show up late in the casting stroke stroke.
So could wave velocity of the tail vary the tail placement?

[GH] Paul,
Frankly, I had not even thought of that scenario .... so cannot give a reliable answer.
I'm not sure that the wave actually could travel at a speed different from that of the loop fly leg.
Seems that if that wave were traveling at a speed greater than that of the fly leg of the loop that it would morph into a different shape.
Perhaps someone else has looked into this .......................

[GH] Answers to my questions on tailing loops caused or aided by circumstances other than casting mechanics ( a valid topic from Guy Manning ) :
Form Don Pendleton :
1. Do you think that there are leader/fly/line/rod combinations which when cast would invariably result in a tailing loop even if the caster has not created a faulty move ?
Yes
2. Are ALL tailing loops the result of problems with casting mechanics ?
No
3. If you answered YES to question 1., please describe this combination.
A heavy weighted fly using too light of a leader. A very Wind resistant fly on too light of a leader. Front taper of a fly line too long for the length of line being cast. Too short of a rear taper for a long line carry on the back cast.
4. We know that certain elements of fly fishing tackle can make it difficult for many casters to avoid making tailing loops. Can you briefly describe them ?
a. Certain fly rods Very slow rods, very short rods, rods with poorly designed tapers.
b. Leaders. Leaders that dissipate energy too quickly, not enough butt mass, an overly long tippet that is too light and dissipates energy long before before loop turn over can occur
c. Lines. Any combination of lines that over load the rod could lead to the wave propagation by the tip either early or late in the stroke.
d. Flies Very wind resistant flies, very heavy flies are sometimes difficult for the beginner.
e. Certain combinations.
5. What role (if any) does the wind play in the formation of tailing loops ? A stroke into a very strong wind either forward or back could leave the appearance of a tailing loop or the caster may be over powering so much that it is forced by an inappropriate application of power.
6. Do you think there are any wind conditions which can result in the caster forming a tailing loop even if the casting mechanics are executed well ? 40 mph plus?
7. Do you think the harmonics of a fly rod (first and second natural vibration frequency characteristics) have anything to do with the formation of tailing loops ? Yes. The speed and amount of re-flex on either side would characterizes the line wave.

[GH] So far, Don is the only one who answered all the questions.
Robert Shigley answered question 4. d. as follows :

[GH] Hopefully some of you are thinking about them.
