Fly Line Stretch and Viscoelasticity

Re: Fly Line Stretch and Viscoelasticity
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.

Re: Fly Line Stretch and Viscoelasticity
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?

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

Re: Fly Line Stretch and Viscoelasticity
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.

The first cast is always the best cast.

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