“… the classical pile cast where the upward trajectory on the last forward cast is very extreme, allowing for the line to fall to the surface in a pile. Be careful to avoid a tailing loop. You will need to back off on your force, open your loop, and angle your backcast down as much as possible.”
That above is a quote from a document I have been reading recently. Well, it is pretty easy to check the validity of that statement in practice.
Fourteen meters of line and leader from the reel to the fluff. No adjustments in force, narrow loop, back cast angled up… and still no tailing loop.
As usual, no tailing loop if you accelerate your casting stroke properly.
