Just look at the contrast between the two lines as they are getting launched, the near side line is thicker near the rod tip and it’s quite obvious thats the one which is the right way round.

Hi Lee

What gaelforce lines are you using? I thought the two long ones where the long head spey from Rio?

In the third video (yesterday on page 20) I am using the gaelforce equaliser 55g, in the second video it was the Rio Long Head Spey, in the first video it was Rio Scandi heads being used.

PS I’m getting flashbacks of organising the WC now where endlessly repeating searchable info becomes my day :upside: :D

With my two hybrid lines I had real problems with the front loaded tapers when casting slow. In particular I had the last section come through very low on the front weighted line.

(Looks like the world of physics has not been turned on its head!)

Cheers, Paul
Reversed Scandi wins this time... :upside:
Both heads had their own running line to pull and yes, I could have had a better leader set up...;)

Sorry mate, didn't spot that you opted for a change in lines, and had only seen the first and second clips :blush:

Ok that’s more like it. :upside: Must have to do with the variation between the heavy front and the light back. Too big a difference and it causes problems. Smaller variation and it flies better reversed. Hmmm! :D

Cheers, Paul
It's an exploration; bring a flyrod.

I can't seem to find any info on the taper online. Is there a diagram on the box?
Paul,
Thanks to Lee taking over a 100 diameter measurements on the 55g Galeforce head it is possible to derive a rho_l vs distance profile for that line as shown below.

Those rho_l values result from backing into a volume mass density of the line based on the total expected mass of the head. As noted in the plot that gives a rho_v of 994 kg/m.^3. Thus the line density is very close to that of water.

It’s fine on it’s own, even the wrong way round 🤓

I made a first run with the line taper kindly provided by Lee:

Although there is some tuning needed, and for that I expect some video analyzis (thanks to volunteers), the comparison in between lines sounds correct: the line in the normal way accelerates whilst the reversed one travels rather slowly. There should be a very late acceleration for the reversed line but given the loop troubles on the video, I cannot say if this will be visible in an analyzis.
So like for the Scandi, there is a logic in the comparative behavior. The Long Spey situation is not yet clarified and if Lee could measure the taper, that would help to understand what is going on I hope. Many thanks in advance.

Standing on the moon, fly rod in casting position, someone has straighten the shooting head (no leader) behind me.
If I do a cast (without shooting) what will happen?

I have no clue - but believe in a loop, a loop propagation and a "kick back" when the fly leg is running empty.
Correct?

Will there be any difference in the "kick back" if I do this "cast" (same speed) with

- a Delta Taper SH 30´/500gr,
- a reversed Delta Taper SH 30´/500gr
- a running line 30´/ 100gr ?
