Fly Line Stretch and Viscoelasticity

[VGB]

I’ve read similar papers Daniel because my experience with DMA was limited to fatigue testing aluminium welds and that was a long time ago. I don’t know what lines he will test but I would think he would be interested in looking at a lines performance within its design envelope.

I'm not convinced the stiffness of the line has any perceivable effect in a fly cast. Here are a few casts with a plastic chain, which as far as I can see, has no resistance to being bent. The cast still seems to progress as we'd expect.

I made casts with various loop widths in case someone would like to examine them.

Cheers,
Graeme

Please could you demonstrate CI task 1 with it, so that there’s a baseline for comparison?

What are you fishing for with that, Graeme?

A handle for his toilet?

What are you fishing for with that, Graeme?

Cars, of course. The road gives it away ...

There’s more potential energy in an overhead cistern than your bog standard wall mounted dunny

That’s quite a step up from puffer fish. Why don’t you wear roller skates?

Hi everyone,
Not sure this helps in any way, but Bruce Richards once told me: SA was running a test about increasing stiffness of a fly line a lot to see the impact on loop shaping. He said the results showed, that a higher line stiffness was no issue at all. Fly lines seemed to be far off being so stiff, that there would be an impact.
Bruce probably could tell a lot more.
This he told me about at least 15 years ago. So maybe further tests were made.
Regards
Bernd

O.s.: Graeme, what fly you using for crocodiles? Impressive line though.

I think the fisherman is the lure if we're fishing for crocs ...
