Here is a recap of some of the things we've discussed during this topic of HAULS :
From Hauls 2 :-
# A HAUL is sometimes simply described as, "A pulling on the line with the line hand during a fly cast."
# There are two different ways of describing or defining single and double hauls.
# School 1., defines a single haul as a pull with the line hand made on either the forward or the back cast, but not on both.
# This school maintains that a double haul is a pull with the line hand made on both back cast and forward cast.
# School 2., maintains that a single haul is a pull with the line hand during the cast without giving back line.
# School 2., maintains that a double haul requires the giving back of line for a pull with the line hand during each cast.
# One way of describing a CHECK HAUL, is: A pull with the line hand after the stop sequence.
# A CHECK HAUL can result in increasing the speed of turnover of the loop.
# A CHECK HAUL can also be used as part of a "bounce cast" to provide a slack line presentation.
# The CHECK HAUL usually shortens the casting distance.
# If the CHECK HAUL is used to turn over a loop where there isn't enough energy in the system to do that without it, it can result in a slight increase in distance. (Otherwise, the cast will collapse).
# The HAUL primarily increases line speed.
# The HAUL can secondarily, slightly increase rod load (bend).
# Another value of the haul, is to divide the work load of the cast between the casting arm and the line arm.
# A haul can help take up unwanted slack in the system.
# Marvin Hedge is given credit for introducing the double haul to competition fly casting in 1934.
# The double haul was taught to Marvin Hedge by Maurice Abraham, aka, "Mooch Adams".
# This history can be found in Jack Berryman's, "Fly-Fishing PIONEERS AND LEGENDS OF THE NORTHWEST".
# For greatest casting efficiency, the best place to stop the haul is as close to RSP 1 as possible.
# Some instructors teach to stop the haul when you stop your casting hand.
# The time interval between the stop sequence of the casting hand and RSP 1 has been measured at close to one tenth of a second.
# Most casters probably cannot discern that 0.1 second time difference.
# The best time to release the line from the haul hand is also as close to RSP 1 as possible.
# An ill timed haul can lead to a tailing loop.
# One way to demonstrate a tail caused by an ill timed haul, is to make a short, sharp vigorous haul during the cast, ending it before the stop of the casting hand and RSP 1.
# Years ago, at least two different "haul tools" were invented. One was a stick like extension of the haul arm. The other was a roller, pulley device.
# These "haul tools" are not allowed for competition casting events.
# Some very good casters haul during the entire cast.
# One recommendation, is to make the haul as you accelerate the fly rod during rod rotation (casting arc).
# A haul makes it easier to pick up a long line from the water. Some call this a "water haul".
# When striking a large fish, a pull with the line hand can help set the hook. This is a haul-like move, but probably shouldn't be called a haul, since it isn't made during the cast. Called a "strip-strike".
From hauls 3 :-
# There are many ways to teach the double haul. These include hauling while horizontal ground casting, pantomime methods, holding the rod still while making haul moves, etc.
# Giving back line is not part of the casting stroke. This occurs during the pause between casts and is often done simultaneously with a drift move.
# Lefty Kreh informed us that it was the late Jim Green had developed the pulley device "haul tool"
# This is described in "HISTORY OF CASTING, Profile/Jim Green, by Chris Korich.
# Some authors look at the so-called, "power snap" (Joan Wulff's term) and the "Speed-up-and Stop" as the same thing.
# From a mechanics standpoint, it is probably more accurate to use terms such as, "smooth acceleration" and "constant acceleration" to come closer to what actually occurs during efficient casting. Having said that, a 1:1 perfect slope of acceleration may not actually be possible in fly casting. Idea is to come as close to that as a caster can.
# Don't ever be embarrassed by an answer or comment, unless you cannot explain your reasoning.
# We learned that a tool used by Australian Aborigines, called a, "woomera" to assist in throwing spears could be considered analogous to one of the Haul tools described, above.
# Some fly fishers (particularly in the salt) use hauls with every cast made.
# Others use the haul primarily to increase line speed for their distance casts.
# A CHECK HAUL can be used while fishing to rapidly turn over a loop and flip it beneath overhanging cover.
From Hauls 4:-
# When to start the haul, depends upon what is to be accomplished. No "pat" answer.
# Not a good idea to start it before the casting stroke or before the start of rod acceleration during rotation.
# For most casts hauling should start somewhere between the casting stroke start and about 2/3rds through it.
# Some casters find it easy to start their haul as the casting stroke begins. Makes timing easier.
# Stopping the haul at RSP 1 reaffirmed.
# Releasing the line at the conclusion of the haul at RSP 1 reaffirmed.
From Hauls 5:-
# Under certain circumstances, a haul can lead to better balance between the forces exerted by the rod hand and those exerted by the haul hand resulting in slightly tightening the loop.
# Different ways of describing double hauls in the fly casting literature reaffirmed in more detail.
# The controversial term, "slide loading" described by Joan Wulff as, "Rod hand moves forward in loading move while the line hand continues to give line back". Also, rod "sliding" along the line as it starts to move forward.*
# CREEP, briefly described as consisting of mostly minimally accelerated (zero to slow) rod rotation resulting in diminishing the available casting arc for the next cast.
From Hauls 6:-
# A haul can help tighten the loop. One instruction is to add a smooth haul, reduce force on the rod, and decrease the casting arc a bit.
# Another scenario: The caster adds a haul and doesn't change the force applied by the rod hand. The haul slightly increases rod bend and the Casting arc is increased a bit yielding a tighter loop.
# Third: A haul is added, Rod hand force increased. The rod load/bend is increased by each. The Casting arc is then increased, to match, and the loop tightened.
# Hauling increased line speed without a COMPARABLE increase in rod bend.
# Putting it another way, the haul usually does not increase rod bend very much.
# Also: For 2 casts with the same line speed, the hauled cast results in a tighter loop because there was less force used by the rod hand and, therefore, less counterflex. (More counterflex can increase the loop size.)
# Hauling can help straighten the tip path as the rod unloads. We are told that Grunde Lovolle has a video showing this.... but we have not yet seen it.
From Hauls 7:-
# We've learned a simple experiment to compare the amount of rod bend (load) with the unstrung rod vs. that achieved by laying the rod on the ground and loading it by hauling.
# Hauling after loop formation, during drift turns the loop over faster, but usually results in decreased distance.
# We learned to be careful about determining the logic behind what can seem to be a "wrong answer". Sometimes this happens when the logic involves a different way of defining something.
# We need reasonably accurate definitions which are, at the same time, easy to understand.
From Hauls 8:-
# We reviewed 3 videos showing the effect of hauls made at different points in the Casting stroke yielding tailing loops at different distances.
# We saw another video showing the effect of counterflex on loop formation.
# More counterflex can pull down the bottom leg (rod leg) of the loop resulting in the loop size immediately increasing. If the line tension due to forward momentum of the loop is sufficient, the loop can then decrease in size.
From Hauls 9:-
# We have no defined parameters for use in coming up with a definition of a short, sharp haul. (Most of us can recognise it when we see it .... but no quantification, here.)
# The hauls seen in the videos yielding tails all ended prior to RSP and loop formation.
# Attention is called to the hauls in the videos being sharp LONG hauls. Not short.
# Agreement that haul hand "follow through" should be minimal if used at all.
# For max distance the haul hand should reach max speed just as the arm straightens coinciding with RSP 1. Top distance casters do this.
# For a tight loop you need a very straight top leg (fly leg) and a very high bottom leg (rod leg).
# The greater the counterflex, the lower the bottom leg.
# The more the rod bends, the greater the counterflex.
# One key to applying a significant haul without forming a tailing loop is to apply power smoothly.
# Another consideration is to make the haul as a, "mirror image" of the action of the casting arm. with respect to length, duration, application of force and end point.
From Hauls 10:-
# We apply what we have learned, above, to self teaching and teaching students.
# Example: Teaching students to stop the haul when they stop the casting hand isn't exactly what happens with efficient casts, but so close as to be a valuable teaching approximation.
From Hauls 11:-
# Note that the videos showing hauls resulting in tails were made for that express purpose... not to demo. hauls.
# The INITIAL size of the loop, assuming a straight upper leg (fly leg), is determined by the position of the rod tip at maximum counterflex.
# The bottom leg "bump" caused by counterflex is pulled out of the line as it is "sucked up" by the tension in the line due to the momentum of the forward moving loop.
# The following rod tip position at RSP 2 determines the final position of the bottom leg and the final size of the loop.
# If you diminish counterflex by reducing rod bend and stop the rod as suddenly and completely as possible, you can get a very tight loop.
# Key to efficient casting is having a loop with as straight a top leg (fly leg) as possible aimed directly at the target.
# The part of the loop that travels the fastest is the top leg (fly leg). It must offer the smallest profile (surface) to the atmosphere. To do that, it has to be STRAIGHT and AIMED AT THE TARGET for greatest efficiently.
# The bottom leg of the loop (rod leg) never does travel nearly as fast.
# The forward speed of the loop is one half that of the top leg (fly leg) and that of the bottom leg (rod leg) combined.
# The analogy of a STRAIGHT arrow, traveling in a STRAIGHT LINE to that of the straight top leg of the loop aimed at the target, may well be a good teaching tool.
# In the video showing the effect of counterflex on the loop: The soft rod resulted in more counterflex so the loop was initially bigger than the one made by the faster rod. This was temporary, however. After a short while, they became the same size. Reason? The rods were fastened together so RSP 2 was the same for each and that determined the final position of the bottom leg once the dip due to counterflex had been "sucked up" by the momentum of the forward motion of the loop.
# The haul should stop as close to RSP as possible. Not after it.
# For students, teaching them to stop when they stop the rod is close enough.
From Hauls 12:-
# The "drag" of the fly should be considered in figuring line speed.
# Wind resistance is proportional to an object's (loop) velocity squared. (Example: Double the speed = quadruple the drag.)
From Hauls 13:-
# Some thoughts about using hauls for various reasons when fly fishing.
