[GH] From Aitor Coteron on propagation of a line wave :
Hi Gordy,
If my basic knowledge of physics isn't wrong the speed of propagation of a wave in a string is proportional to the the tension of the string.
As seen on the videos previously linked a powerful and faulty haul produces a wave that will create a tailing loop; it also gives more tension to the line, and more tension implies that the wave going from the portion of line near the tip of the rod to the tip of the line propagates faster. But, given the same stroke, a fault at the beginning will always show a tail that manifests itself later than a fault at the end of that same stroke.
Here we can see that a fault around the middle of the stroke produces a tail around the middle of the loop's life:
I hope that this makes sense and dissipates some of the doubts about this issue.
My best,
Aitor

[GH] No doubt remains in my mind. You are correct.
Great video of the line wave !

[GH] From Ckling Ling :
Hi Gordy,
Certain rod/line/leaders/fly can induce a tendency to tail but not invariably depending on how good the caster is. A good cast has smooth loading and unloading which enables the line and leader to unroll smoothly. The unbalanced combination gives rise to a hinging effect in the unrolling line. The other reason is if there is a significant mass change in the line to fly, different momentum is created which can affect the unrolling line.
1. Heavy and/or wind resistant flies
2. Long fine leaders inappropriate for size of flies, too abrupt a step down of diameters or poundage
3. Short heavy shooting heads, heavy sink tips, level lines?
4. Long floppy rods especially one with poor dampening and heavy swing weight. Certain older rods with uneven hinging type of bending.
A very strong wind can blow a loop out of shape and even collapse it, but the tendency to tail is more likely due to slack caused by the opposing or sidewind in the previous stroke.
So I guess the worst combination would be a long floppy rod, short heavy shooting head, long thin leader and a heavy wind resistant fly casting into strong headwind!
Regards,
Ling
