An answer from Steve Rajeff on questions re. two handed casting with respect to choices of rods and lines:
Hi
Gordon,
Regarding shooting head
length for overhead casting of two handed rods:
Just like for single
hand rods, there is a weight and length that makes for the easiest
cast.
9 foot single hand rods
work very well with around a 30 foot shooting head and a weight of two line
sizes heavier than the rod is rated. If you use a 10 foot rod, the shooting head
that casts the nicest is a bit longer, and some would say around 35 feet. This
length of head comes close to matching a casting stroke cycle time that feels
good when casting the 10 foot rod.
Similarly there is a
length and weight of head that feels good for overhead two hand casting.
Using a 14 foot rod, 35
feet will feel short. Around 45 feet will feel like a nice length for timing and
stoking the cast. If the rod is much shorter, like the new Cross Current 11’3”
two hand rod in either 10/11 or 12/13, the head length that feels nice is around
35 feet, (and was developed around the then prototype Airflo Beach
Line
for two hand rods. For
some reason, after the rods were rated 10/11 – 425 grains my brother Tim
decided to lable the line as an 9/10 430 grains.) The suggestion from Simon re a
Scandinavian shooting head is not
a bad suggestion. As
produced and available from
for cutting the butt
end to suit various length rods for Scandinavian casting. They are in the
area of 36 to 40
out of the box. If you
find one that matches your rod, without cutting, then you will have a pretty
good line for overhead casting. There are three main categories of spey rods,
with at least two other sub categories.
The sub categories
include an emerging two hand for salt water, and an all purpose rod group for NW
steelhead. Greased Line rods, designed for the long belly lines, handle
the heaviest of all spey lines, and cast the heaviest lines. It is possible to
make a very heavy head for say a 9/10 or 10/11 Greased line type rod and cast
farther than any other spey action. Scandinavian rod action is the fastest
taper, and actually would make a tighter loop in casting, but they are not as
stiff as their counterpart in Greased Line rods, and so the GL will handle a
heavier line, and still cast farther. The
Two hand rods will
overhead cast easier with about 20% less grain weight than the working weight of
the line for which spey casting method, the rod it is rated for. An 8/9 Delta
Taper is around 630 grains. To comfortably overhead cast the rod that matches
this line, a shooting head, of around 500 grains should feel
right.
Length of head that
times well in overhead casting, seems like 3 to 3 ½ rod lengths. A 13 foot rod
should cast a head of 39 to 45 feet very nicely. A 15 foot rod should cast a 45
to 52 foot head very well.
My big gun tournament
17 foot overhead rod is perfect with 58 to 60 foot head, and falls into the 3 –
3.5 factor.
This is all the
ramblings I have patience for.

From Guy Manning (MCCI)
The
first thing to understand about spey/skagit/scandi lines is that they do not
follow the AFTMA standards for singlehanded fly lines.
See:
http://www.kolumbus.fi/sauli.liukkonen/SpeyLineStandard.pdf
for the standards for DH lines. The next thing to understand is that the
different types of lines are designed for different fishing conditions (and
often different rod actions). Skagit lines are for getting low in the water
after Pacific Steelhead and often 90 degree or better casts across stream using
slow action rods. Scandi lines are designed for casting across and downstream
while swinging flys just subsurface to Atlantic Salmon with fast actioned rods.
Many of the mid belly lines have interchangeable heads to allow for fishing at
different depths and are often a better choice for an “only” line for those of
us who can’t afford one of each to cover every conceivable situation.
These guidelines are generalities and exception can be noted in all cases.
Scandi
lines are usually cut approximately 2.5 times the length of the rod. Scierra has
an interactive tool that takes into account line, fly size, leader, height of
caster and rod length. See: http://www.scierra.com/?category=-1
for the tool. Again this is for scandi lines, which are usually floating lines
designed for Atlantic Salmon fishing conditions. But these heads
would also work well in an overhead casting environment and load the rod well.
So if using a 12 ½ foot rod you would want a head about 30 feet long. If using a
14 foot rod your head length would be more toward 35 feet long. If you
preferred a longer head for a bit more distance then you would follow the
shooting head standards in the link above to determine the weight of the
shooting head. It takes longer for a 40 foot head to turn over than a 30
foot head, thus more distance.
This
can all be somewhat confusing, but it is a lot better than before the standards
were published. At least now we have some guidelines. Most heavy duty DH casters
play with their lines constantly trying to come up with the ideal for the rod
and conditions they are fishing in. Al Buhr is a prime example of this.
If
you now have all of that straightened out, take a poke at understanding Skagit
lines. Go to :
http://www.ggacc.org/docs/Sites/1/Bulletin-2006-07.pdf
This
is an article by Bob Pauli of the Golden Gate Angling and Casting Club. It is a
well organized presentation on Skagit lines. It show that much of the research
in our sport is still being done by the everyday
practitioners.
Simon
writes: “...when you attach a heavy line to a thin shooting line, there's
a tremendous difference in weight at the point where the two lines join. This
disparity in weights becomes an issue when you're casting long distances. As the
line travels out, the rear end of the heavy shooting head pulls down the running
line and the back end of the loop, causing the line to land rear-end first,
which translates to a loss of distance...”
I don’t agree with this as written, but I would not
want to comment unless I had the whole article in front of me. Dermon may be
misreading this. I don’t think Simon is talking about hinging here but possibly
overhang.

Got it! So this suggests that drift relates to a motion in false
casting, while F/T relates to a motion in the presentation cast.
O.K., this is better, because, although I agree with what is said
here, 100%, my notes from earlier conversations led me down a path
that suggested that maybe drift was exclusive to the backcast, and you
are saying it is not.

Michael....
When dealing with descriptions and definitions, we must remember that at the present state of fly casting lexicon, there is no pure list agreed upon by a significant body of experts. This is why we have been working with a glossary committee to change that by coming up with a list of definitions agreed upon by the FFF Casting Board of Governors. We have accomplished a great deal .... but have a long way to go to completion.
This is why you will hear many, "definitions" for the same term.
Joan Wulff writes that FOLLOWTHROUGH is performed only on the forward cast, while she calls the repositioning of the rod in the direction of the unrolling loop on the back cast, DRIFT.
Our committee has not yet formally defined FOLLOWTHROUGH .... so what I have given you, is my personal point of view.
