Impact with Indicator Tip
Strength & Stretch
Core materials for Impact fly lines have a stretch rate of about 4 percent. Traditionally, the average stretch of a fly line is about 15 percent! The low-stretch core of Impact lines translates back to the angler as well as the rod to assist in casting, connectivity to the fly, and accuracy. Hook sets are more positive. When casting, the load on the rod is immediately transferred to the end of the line, and there is no longer an energy-sucking lag in the dynamics of the cast. This allows the angler to pick up more line and heavier flies without exhausting the energy stored in the rod during a cast. To illustrate, think about picking up a heavy weight with a bungee cord as opposed to a stiff rope. Which method will pick up the weight higher and control the lift better?
The polyester coating of Impact fly lines does not contain the volatile chemicals that must be added to PVC in order to create a fly line. This shift in technology is important to maintain the durability of the line. Previously, these chemicals would constantly leach out into the environment. This is why we steer away from PVC baby toys and food containers—they emit poison. As those chemicals migrate out of the plastic, a void is created in the compound. Not only does this alter the compound from its initial characteristics, but that void forces the compound to crack over time. This is where the circumferential cracks on a PVC fly line are born. Add dirt, oil, and other foreign debris to the cracks and performance degrades. Impact lines do not lose material over time, and therefore do not crack. This is important in the overall durability of the line and its performance longevity for the angler.
Fly fishing is a year-round sport and takes place in a variety of locations and environmental situations. For years, fly lines have been marketed as cold water, arctic, tropical, still water, warm water, etc. This delineation of the product line causes complexity for both anglers and fly shops. Impact fly lines are suitable for all temperatures. A Monic Impact fly line will perform equally well in all temperatures, whether it is used for winter steelhead with snow on the riverbank or if it is being directed toward tailing permit from the bow of a hot skiff in the tropics. This saves the angler time, money, confusion, and space.
The coating on Impact lines is a polyester blend. Historically, the industry has been made up of fly lines that were coated with either PVC or polyurethane, as well as polyethylene. The material used to make Impact lines costs 10 times more than other lines, yet the consumers’ price of Impact lines remains competitive with the rest of the market.
Polyester, unlike the others, is a very low memory coating. Imagine picking up a wadded-up PVC poncho, or inflatable raft from the floor of a tool shed. You’ll notice that those items retain that exact shape. Now imagine picking up a polyester suit that has been laying on the floor of a closet since the 70s. Shake off the dust, and it’s ready for your next disco party—no wrinkles.
When you add things to the coating, such as micro balloons to make it float, those particles make their way to the surface of the fly line and create an abrasive quality. This abrasion causes cuts in the hands and noise on the guides of the rod. The smooth finish found on Impact lines remains smooth over time and has a better feel in the hand of the angler.
