Newbie leader question

Knowing the properties of various things allows one to make better
choices in their use, or even to avoid them, and also explains why
they behave as they do. The "blurb" published by various fishing
tackle manufacturers is virtually never accurate, or even useful. In
the majority of cases it is merely advertising bull****.

Pretty good series of posts
Thanks man.
I understand fibers as I have worked developing and inventing specialized
non wovens for the textile industry - specifically embroidery
No more flurocarbon for me.

Fine nylon is more prone to retaining memory anyway. The longer it
remains coiled the more memory it retains. Also, if such coiled
leaders are kep in a warm place, or left on the dashboard of a car
etc, the memory is programmed immediately. The only way to remove it
is by heating and then cooling.

The same applies to any thermoplastic material, including fly-lines.

OK

So that the next time I use nylon leader will I will have to do this
repeatedly-
Sometimes more than once a day? - Dependant on weather and water conditions?
If so I am staying w fleuro carbon

Fred

No, you only have to do it once. In cold weather, placing the leader
in a hot cup of coffee for instance, and then holding it straight
while it cools ( It is NOT necessary to stretch it), will ensure that
the leader remains straight.

The same applies to fly-line. Although you may need a larger coffee
cup.

Thanks Mike. This was very helpful. This will help me straighten my
remaining leaders so I won't have completely wasted my money on
them.

Cheaper to make your own anyway. Try this;

Just add tippet as required. They work as well as furled leaders.

If you find they are a little "springy" after completion. Dip in very
hot water for a few seconds ( ten...twenty seconds) and then stretch
slightly while allowing to cool.

Stretch it yourself?

No, this is done after extrusion. The different types of nylon also
have different melting points. The process of "stretching", along
with some other information, is described here;

http://web.utk.edu/~mse/pages/Textil...n%20fibers.htm

It is more or less impossible to do any of these things in an amateur
workshop or similar. They are industrial processes requiring special
machinery and know how. I developed and built some electronic
monitoring equipment for some process lines, and learned quite a bit
about the processes while doing so.

Sorry, once again, I don´t have any specifics for fluorocarbons. I
only have some very general information on fishing lines.

Regards and tight lines!

For a very general explanation of this, see here;

As you can see, they also claim a unique molecular fluorocarbon/nylon
bonding system.

Yes, I also have some experimental samples of "Carbon Bond" line,
which is incredibly strong for its diameter. I have a 1000 meter spool
of this with a diameter of 0.01 mm, ( which is about equivalent to 7X)
and a breaking strain of ~ 5lbs. This is about two and a half to
three times the normal breaking strain of such a diameter in ordinary
nylon etc. It also has very little stretch. I have no details on its
structure or properties as yet, or even what it exactly is, and it is
not available to the general public.It may not go into production at
all, it seems the firm is having marketing problems. I did a few jobs
for them on their machinery, as a favour to one of the partners.

I have not used it for fishing yet, but I imagine it will be more or
less perfect tippet material for trout fishing with small flies.
( assuming it is environmentally friendly etc) The line I have is a
light translucent brown colour, ( looks like very fine clear brown/
amber nylon) which at present is the only colour available. I don´t
know why. This of course assumes that one would want to use such
extremely strong tippet in the first place. If you have to pull for a
break, then something has to give, and it is always better for the
tippet to break than anything else. Also, it is extremely unlikely
that very fine hooks will stand the amount of pressure one could exert
with such a tippet. These things are often far more complex than one
might imagine, and one thing leads to another.

Such extremely fine tippet will also not turn over a standard dry fly
in larger sizes, because the thinner the tippet, the less ability to
transfer power along its length.

The Yo-Zuri is also first class, but all these lines are bad for the
environment, and so I don´t use them.

You can find the RIO specs ( which are very reliable) here;

I can´t give you any info on de-glinting the fluorocarbon, because I
don´t know what effect it might have. It is perfectly safe and easy
to de-glint nylon with a paste of Fuller´s earth, ( Mixed with soap
and glycerine), and I consider it imperative to do this. But I don´t
use fluorocarbon lines, coated or otherwise, and I don´t know if this
method works on much of it. It did not work very well on some of the
lines I tested, the coating is extremely abrasion resistant. So it may
not be either easy or sensible to abrade a fluorocarbon coated line,
and I don´t know whether it will work at all on "100%" fluorocarbon
line. It may cause the line to waterlog? Which would weaken it
considerably. I really don´t know.

Regards and tight lines!

PS. It will also make it a lot more visible! The refractive index
depends on an unmarred surface! Which is another reason the
"invisibility" is more or less useless, and basically just a marketing
gag. Glinting line will spook a lot of fish, and if you can´t de-glint
it is practically useless. It is to me any way!

PPS I don´t use many flies smaller than a #16, so the line is
actually of very little use to me, except for a couple of special
tactics, one of which is fishing weighted flies deep on fine tippet.
The finer the tippet, the faster and deeper the fly sinks.

BTW, some people in ROFF think that 7x is NEVER useful. I disagree. I
use it when fishing the Trico hatch at Silver Creek (and pretty much
only then). I've landed sizable fish on 7x, and lost few, too.

I find 7x can be very helpful to achieve a drag-free drift while nymphing.
There's less profile for the current to have its way with.
