Re: Line configuration affect on rod
Hi Vinny,
Grand slam is .75 heavy. From SA site:
“ Overweighted by .75 sizes to load rods quickly”*
Ballistic pro is bang on, AFFTA.
GS head weight 300 Grains
I don’t know the head weight of Ballistic but it’s 210 at 30’. There is a rear taper in there to make it sixty feet so it’s unlikely to be 420, but it’s almost certainly heavier than the GS. But I bet it doesn’t feel that way! The rod might not know, but I’m sure we do.
Cheers, Paul
*interesting that SA write this. I did some testing of lighter lines making faster shots than heavier lines. Heavier lines don’t load the rod quicker, only more, which in turn slows the shot.

I've always taken that little bit of marketing to mean "it loads the rod with less line outside the tip".Paul Arden wrote: ↑Thu Apr 18, 2024 4:01 am *interesting that SA write this.

So for those guys who are stripping their lines in more than they should, the line will "load the rod" sooner in their casting cycle than a true-to-label line does.
Of course, I could be wrong. Who knows?

Hi,
in my case was it a 18g casting plug, a short and a long shooting head and I've described my findings in #33, also somewhere in the archive is the discussion. I've snapped often enough casting plugs, usually this happens after non-smooth acceleration or if you forget to release the line My guess is an overshoot of the force function for a very brief period.
Greetings,
Torsten

Re: Line configuration affect on rod
I normally fish the fly in close when fishing, so have to work the line out again. I think it comes from the big spring idea, that the road loads more with a heavier line, which is true, but this extra loading actually slows the stroke.
It’s obviously not what we do when we want to generate high line speeds. Otherwise we would be using softer rods that load more, instead of pokers in the WCs.
Heavier lines can be an advantage, but that has to do with the line itself and not what it does to the rod.

How long is a long shooting head Torsten?

Are you using “load” when you mean “bend”?
When a given mass is moved by a given force by two
levers of the same length but different stiffness isn’t the load the same???
Does a softer rod under load hold more elastic energy than a stiffer rod under the same load? Or do the rods hold the same elastic energy just in a different shape???
I’ve never been clear on this.
Thanks
George

Re: Line configuration affect on rod
Sorry in that last sentence I should have written “bend” not “load”. You are correct George.
I believe that stored elastic energy would be the same between softer and stiffer rods under the same load. I don’t know if or how the dynamic loading changes this.

Re: Line configuration affect on rod
When we simplify the rod as a spring, the softer rod stores more spring energy for the same load.

Re: Line configuration affect on rod
AFAIK it was ~20m for the long and ~10m for the short one; my premise was however to keep the fly/rod leg straight. When it's warmer I can try to repeat the experiment, perhaps I'm getting a different impression.
Re: Line configuration affect on rod
Hi Torsten,
It might be worth repeating the experiment without hauling? I think that the issue is to do with your straight premise, any difference will be so slight that you either won’t detect it, or your hauling hand is tidying up the line layout.
