Re: The practical side of considering loops as waves: Teaching and Self Improvement

Save for outlining a really nice-looking fish that morphs into something more Amoeba-like, I don't think you have removed tension from that cast, Graeme. A wave needs tension to propagate, and that fish loop still propagates. The best way to remove as much as possible tension from the rod leg is to ...

Just a new variation on the dolphin nose.

And check the markers through the loop, it still propagates!

Re: The practical side of considering loops as waves: Teaching and Self Improvement

Do I need to take a whole bunch more videos? I chose one of half a dozen casts. Or you guys can go out and play with it yourself. You've now seen it in action. Please go and experiment for yourselves. Hi Graeme Thanks for this fascinating video. It is a pity that the sign on the black wall obscures...

Re: Rod length to distance, it does not make sense

Hi Bart

I take it you were hauling the hand casts?

Cheers,
Dirk

As James neatly pointed out in his FP “the Big Spring”
Hi Paul

A link please?

Is there a page where one can find archive FP's?

Cheers,
Dirk

Re: Analysing loop propagation

The superbubble looks at casts as swivel cones in 3D And the base assumption is that the sum of all rod tip paths is a sphere ( the superbubble) I enjoyed that again thanks, Michael! Your 3d conceptual is a bit lacking in detail, mainly because it lacks translation, I think. A more realistic D-stic...

Re: Analysing loop propagation

If all we ever do is mathturbate here on a forum, it makes no difference if the loop is a wave or not. However, it has real world consequences for me when I cast and teach, so exploring the concept is not a frivolous pursuit. I use it every time I cast. Well put, Graeme! I, for one, would be very i...

Re: Analysing loop propagation

A jerk is readable in Gordy's pull-back cast rod leg velocity and at the same time an opposite direction jerk is readable in the fly leg velocity - centripetal force explains it for me. Dirk, Not only is it readable, the jerk derived from the measured velocity profiles in that pull back cast can be...
