Walter & Group......
From Walter Simberski:-
(On the idea that most modern rods can handle lines of greater rating than
those of the rods as the reason many casters, "upline" when using shooting
tapers).
Sorry Gordy - I have to take exception to that. I
was hoping someone else would raise this so I could see it done in an
non-antagonistic fashion
but let's see if I can handle it. I will be quite
happy to accept my lumps if I'm wrong though. I'll also take the short
answer/long answer approach.
Short answer - All 6 weight rods are in
reality 8 weight rods? Not true.
Long answer - While I realize that a very fast
or ultra fast 6 weight may have some
characteristics in common with a medium or medium fast 8 weight
there
are a number of factors that determine the action
of a rod - for example, stiffness of the base material, shaft diameter, wall
thickness, taper, length, placement and weight of the guides and wraps used to
finish the rod. So even though fiberglass has a modulus of 6,000,000 and modern
graphite rods
range from 5 to 9 times that we can't just say that
the higher modulus material always yields a rod that is better suited for a
higher line weight.
In addition, rod manufacturers look at different
ways of rating rod actions. Tip deflection with a given load is the most common method but how fast a
rod goes from loaded to rsp, and the position
where the rod bends under a given load are others. So the idea that all 6 weight rods today cast an 8 weight
line in the same
fashion as an 8 weight rod of a few decades ago simply can't be
quantified.
I realize that most people prefer medium fast to
fast action rods but there are a significant percentage of people who prefer
ultra fast rods or medium action
rods. Another consideration is that if I was to
find that the 3 weight rod I've purchased for small fish on small streams so
that I can make delicate dry fly
presentations is in reality a 5 weight rod and I
have to go through all kinds of contortions with line selection and leader
design to get those delicate casts
I would probably be a bit annoyed with the rod
manufacturer.
Recommending that shooting tapers should always be
up-sized 1 or 2 sizes from the rod rating is overly simplistic. As in all
cases when helping a
student choose a rod a line I recommend casting the
potential combinations until the student finds the one that has the preferred
feel. Yet another
reason that fly casting is an art rather than an
exact science.

Walter ....
GREAT STUFF !!!!!!!!!!!!!!!!!!
You beat me to it. (I was about to hit the sack after a bout with
tarpon this morning..... but you fired me up.)
Of course all 6 wt. rods are not really 8 wt.
ones.
You are also absolutely correct that increased modulus does NOT necessarily
result in greater ability to handle heavier lines. It also holds true,
that not every good caster, "uplines" when using shooting tapers, and those who
do, don't do so with all rods.
Bottom line, as I see it, is that stiffness, alone, does not result in
greater rod power. ONE CAN HAVE A SOFT 8 WT. ROD WHICH IS ACTUALLY
MORE POWERFUL (able to handle a bit more line wt.) THAN A STIFF 8 WT.
ROD OF HIGH MODULUS.
Going beyond that simplistic concept, we note that the best fly rod designs
for fishing handle a wide RANGE of line weights. That is an important advance in
the technology of modern fly rods.
Even the idea of rating a rod's, "power" as its ability to handle line
weights is narrow minded. Big game fly fishermen don't look at it that way
at all .... they rate a rod's, "power" in terms of the lifting limit of its butt
section in some cases, and of it's "power" to subdue large fish by the tip and
mid section flattening out so the angler ends up fighting the fish on a
relatively shorter lever arm in others.
At our Continued Education Course which we gave at Marlboro, Mass. this
winter, Tim Rajeff gave a clear presentation on the subject of relative rod
power. I'll see if we can solicit his comments on all this.
Putting it another way, I look at it as the power of a rod being determined
not by the modulus of its fibers or its composite structure alone, but more by
its DESIGN PARAMETERS.
