Line System
Show Answers:

  1. Fly Line Backing
    • Spectra™ — Super Braid
    • Spectra™ ― Ultra-thin, Ultra-strong backing made with braided polyester.
    • Narrow diameter
    • Twice as many yards of backing on spool as equivalent 20-pound test Dacron.
    • Negligible stretch
    • Doesn’t add compressive force to the reel spool
    • Abrasion resistant (Highest)
    • Won’t rot
  2. Line Core Materials
    • Braided multifilament nylon
    • Braided monofilament nylon
    • Single-strand monofilament nylon
    • Braided multifilament polyester (Dacron)
    • Kevlar
  3. Fly Line: Braided Multifilament Nylon
    • Standard core material used in the majority of fly lines today.
    • Excellent material for most freshwater fly-fishing applications
    • Trout, bass, steelhead, etc.
    • A very limp material, does not add significantly to line stiffness.
  4. Fly Line: Braided Monofilament Nylon
    • Braided monofilament is essentially “glued” together, and the combination of coating and core becomes stiff.
    • Make the best casting and shooting lines available for saltwater angling.
    • Bonefish, tarpon, etc.
  5. Fly Line: Single-Strand Monofilament
    • Permits the production of a crystal clear line, sometimes called a “slime line”.
    • Designed for use in saltwater; has a rather stiff, heavy core which produces a stiff fly line that works well in the heat.
  6. Fly Line: Braided Multifilament Polyester
    • Lines designed for tournament distance casting; less stretch.
    • Some shooting lines which are used primarily with heavy shooting heads for big game fish.
  7. Fly Line: Kevlar
    • Memory problems due to the no-stretch Kevlar core.
    • Durability problems because very difficult to adhere line coatings to.
    • Standard nail knots cannot be used to tie on leaders; coating slips off.
  8. Fly Line Coating Materials
    • Polyvinyl Chloride (PVC)
    • PVC is the main base material found in most fly lines today. Can be modified easily.
    • Polyurethane
    • Additives
  9. Coating Additives
    • Hollow glass microballoons
    • Trapped air bubbles
    • Pulverized tungstenUV inhibitors
    • Hydrophobic compounds
    • Lubricants
    • Stiffening / Softening agents
  10. Basic Coating Process
    • Core material is passed through primer solutions and cured in an oven to improve adhesion of the coating to the core.
    • The primed core then goes into the liquid-plastic coating solution and on through a computer-controlled, variable orifice die that dictates the diameter of the taper.
    • Line is thermal-cured.
    • Lines are made continuously, end-to-end.
  11. Weight-based Rating System
    • First 30 feet of a fly line determines the AFTMA weight of the line.
    • Minus any short, level tip section.
    • Established in 1961 by AFTMA.
    • American Fishing Tackle Manufacturers Association.
  12. Selecting Fly Line Size
    • 3-, to 5-Weight Fly Lines
    • Small light flies, such as trout dry flies, offer little resistance and can be cast with very light lines.
    • 8-, to 11-Weight Fly Lines
    • Large wind-resistant flies, like bass bugs or saltwater flies, require heavy lines
    • Wind conditions can dictate heavier line.
    • Bonefish flies are small; 7-8 Wt. rods recommended.
  13. Line Color
    • Usually fish view a fly line against the bright background of the sky, which makes the line appear dark, a shadow.
    • The real key to preventing fish from being spooked by your line is to avoid casting where they are looking.
    • Seeing the line helps beginners to analyze casting problems, allows better control of the line’s drift and better strike detection.
  14. Problems When Tip Sinks
    • Creates Micro-drag during dry fly fishing by pulling the leader straight; and sometimes even pulling the fly under.
    • When nymphing, harder to see subtle strikes of a subsurface trout.
    • Creating a huge surface disturbance when line is picked-up off the water.
  15. Issues with Floating Lines
    • Specific gravity of floating lines range from .60 to .96
    • So, why does the front tip always seem to sink in the water?
    • The front taper has the thinnest coating (least amount of low-density filler) over a braided multifilament nylon core.
    • The nylon leader has a specific gravity of about 1.2, heavier than water.
  16. Saltwater Fly Lines
    • Floating lines with densities nearer 1.0 are usually designed for saltwater use, because saltwater is more buoyant than freshwater.
    • Saltwater lines are nearly one size smaller in diameter than comparable freshwater lines.
    • Narrower diameter cuts through strong winds.
    • Never use a saltwater line in freshwater because they do not float well.
    • Coatings are formulated for tropical temps!
  17. Nymph Lines
    • Specialty lines made for western nymph fishing, i.e. a couple of split shot and float indicator.
    • Larger-diameter line tips that float better than standard lines.
    • Convex-compound taper.
    • Easier single-handed Spey casting.
  18. Sinking Lines
    • A WF-9-F weighs the same as a WF-9S fast-sinking line.
    • Sinking line is much smaller in diameter.
    • Tungsten filler.
    • Type I sinks slowly; Type 8 sinks fast.
    • LC-13 fastest sink rate.
  19. Basic Types of Taper
    • Level (L)
    • Same diameter from end to end. “Kick” because they have so much undissipated energy left when the line straightens. Poor delivery—Awful to cast. Inexpensive.
    • Double taper (DT)
    • Identical tapers at each end. Not well suited to distance casting. Good roll casting line. Delicate presentations can be problematic.
    • Weight-forward (WF)
    • Very good distance casting; Trying to roll cast with the running line of a WF line extended from the rod tip is very difficult, if not impossible. Therefore, you are limited to ~ 40-foot roll cast.
    • Specialty Tapers—Bass-bug, saltwater, nymph, XXD distance, et al.
    • Shooting taper (ST)
    • Weight-forwards without the running line; typically 30’-38’ long with a loop on the back end to which attaches a special shooting line, ex. Mono. Great for achieving maximum distance and ability to change lines easily.
    • Difficult to control; not easy to cast accurately, can only be roll cast or mended at short ranges.
  20. Function of Rear Taper
    • It provides a smooth transfer of energy in order to maximize line control and the ability to roll cast, reach cast, mend, and pick up line.
    • Especially true when carrying a lot of line out of the rod tip.....past the belly, and well into overhang.
    • The rear taper makes long mends easier.
    • It serves as a smooth connection between the belly and the running line.
  21. Over-, Under-Weight Line Size
    • Anglers planning to purchase a short-headed line specifically for bass, saltwater, or other application would be well advised to buy a line one size heavier.
    • The light, small-diameter running line makes longer casts difficult, ex. 50’ aerialized.
    • Purchase a line one size lighter with a longer-than-standard head if casting long distances.
    • Avoid opening the casting loop, diminishing line speed, and reducing distance.
  22. Types of Compound Tapers
    • Concave-compound tapers
    • Mass of the line decreases rapidly when the first part of the taper is reached, dissipating much of the cast’s energy. Angler can deliver fly very delicately.
    • Convex-compound tapers
    • Taper delays turnover speed and dissipation of energy because the mass of the line is not decreasing rapidly. Angler can load the rod quickly and cast long distances; particularly with larger flies on windy day.
    • Triangle taper
    • A convex-compound taper. The head of the line is actually tapered for its entire 40 feet length. The saltwater Triangle tape has a 30 foot long front taper.
  23. Sink Tip Lines—Solution
    • Open the casting loop and slow the line down as much as possible!
    • The tip of a sinking-tip line is very heavy and dissipates energy poorly.
    • To compound the problem, lines with very high density tips are very small in diameter and offer less wind resistance even when they do finally accelerate.
    • Roll cast the line up to water’s surface.
  24. Fly Line Maintenance
    • Cleaning fly lines.
    • 3M Scientific Anglers Cleaning Pad & Dressing
    • Only use with Mastery Series lines (internally lubricated with softening plasticizers)
    • Top coated lines must be “dressed”
    • Protecting fly lines.
    • Avoid heat, light, & solvents
    • Mucilin is very damaging to modern fly lines.
    • Insect repellents, motor fuels are too!
    • Store in refrigerator or freezer
