Walter & Group....
I asked Bruce Richards if he knew of any fly
lines which had cores to which had been added secondary materials such as metal
particles, etc. This is his answer G.
:-

Hi Gordy,
The only lines I can think of that would have metal in or
on the core directly would be lead core, lead wire with nylon or dacron braided
over the top.

Bruce,
Years ago, we used to cut sections of
lead-core trolling line to make sinking heads. We used a postage scale to
measure the weight of a hundred foot coil, then cut lengths to get the
grain wt. we needed. (Easy to do since this was a level trolling
line.) Advantages: 1.
Available. 2.
Inexpensive.
Disadvantages: a. No taper. b. Didn't cast
well. c. After a few days of use, they tended to crack. d. You couldn't
make a heavy short taper or a lighter long one.
(By doing it this way, we made the
assumption that the specific gravity of the line was uniform. We might not
have been right about that.)

Fly Line Quiz ----- Comments.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From Bruce Richards (On our quiz on fly line
coatings & silk lines ) :
Hi Gordy,
Good questions, I can't answer them all! I haven't
paid much attention to silk lines lately....
I don't know if you intended for #8 to be a trick
question or not.... Mass is the quantity of matter in a body (its weight, in
essence). As asked, the question can't be answered, it is like saying which
material weighs more, lead or balsa wood. It obviously depends on how much you
have. If a trick question, well done! If not, I think you meant either density,
or specific gravity, not mass?
Bruce
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Bruce .... Not meant to be a
trick question..... inartfully worded on my part ! Of
course it should have read MASS PER UNIT VOLUME or SPECIFIC GRAVITY.
Almost everybody answered it as though I'd worded it correctly
(!)

From Peter Minnick ( He had one of the best
quiz scores.) :-
Thanks Gordy....It's amazing how every time I read Bruce's MFL I not
only learn something but I have a better real understanding of fly line design
and how it impacts the cast.
I've downlined my 7wt. GLX to a 6 wt. line and I can control all the
distances so much better. I took the 10wt. tarpon taper to the beach yesterday
and it casts very well in the surf...I'm trying different rods and lines for
this and J Valle is coming in Sept. with some switch rods and will be joining me
in giving a demo at the Montauk Fishing Party which I'll forward to you...I
think it's going to be well attended and will be the 1st of an annual
event. If so I've got Steve and Bruce on file to attend...

Question from David Diaz :
G: The line quiz was excellent, a real
workout. In reference to numbers 47 and 48, how would
one measure the speed of the free- and attached-legs?
Thanks, DD
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DD....
Several years
ago, this was done with timed video, the casts being made with what was known as
the "ZEBRA LINE".... A fly line with alternating black and white
sections.
Best,
Gordy

Comment: Others may have used different methods of
which I'm not aware. G.

Dusty Sprague:
Gordy,
The article by Bruce and Noel is already in the Master Study
Guide.

Dusty... Thanks !

it.) G.

SHARP POINTED LOOP
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From Ally Gowans :
Hi
Gordy,
Good answer as expected
from Steve. In effect what he describes is maintaining the rod tip path in
alignment with the following line inertia and minimising the effect of SLP
deviation due to counterflex (which often appears as a rounded loop shape when
the tip path rotation curves away from the line direction). Naturally a
significant deviation from the line inertia will lead to a rapid speeding up of
the rod tip because its loading is reduced significantly and often it throws the
noticeable transient dip in the line which really illustrates the path being
pulled out of alignment.
