Floating Lines

All four taper designs: Level, Weight Forward, Double Taper, and Shooting Heads are found within Floating lines. The Weight Forward taper is by far the most common. The lines vary depending upon what type of fishing conditions and rod actions you are utilizing. The following table shows a sample of floating lines from Scientific Angler, Cortland, Rio, and Airflo. There are plenty more that are not listed as there are many floating lines specific for certain uses. These selections are based upon needs for All-Purpose, Spring Creeks, and Distance Casting situations.
The "weight" classification is one that has been established by the manufacturers. For instance a WF3F is Weight Forward, 3 weight, Floating line. This line would be used with a 3 weight rod. By examining the lengths of the various head components and the running line, you can get a good idea how these components will affect the line performance. For instance, a distance casting head will be much longer than one designed for Spring Creeks.

Mastery MPX Mastery Trout Mastery Expert Distance Frequency Trout Mastery Euro Nymph

For years, the gold standard in the Scientific Anglers lineup was the GPX taper. Redesigned with more mass toward the front of the head, the MPX provides the same benefits of the GPX, with an added emphasis on presentation. The power is still there, only with an added bit of finesse.The Mastery Trout line is ideally suited for chasing browns, rainbows, cutthroats, and any other trout you can imagine. Trout excels in short-to-medium distances with dry flies and smaller nymphs and streamers. Expert Distance is an amazing trout fly line masquerading as a competition line. Designed with an extra-long head and rear taper, the Mastery Expert Distance is excellent in the wind, provides smooth distance casting, and lets you throw mends you didn’t think were even possible. The Frequency Trout, a double taper line, features a versatile, mid-length head ideal for delicate dries; however, it also provides great line control for nymph rigs. If you’re a trout angler, this is your Frequency. Mastery Euro Nymph line is built to FIPS Mouche standards, but designed to simply catch fish, the Mastery Competition Nymph line is as simple as it gets: 80 feet of level line, in either a floating or an intermediate density. It doesn’t matter if you’re in an international competition, or just trying to outdo yourself, the Competition Nymph line will perform, fish after fish. Specifically designed for European-style nymphing, if you’re looking for the thinnest, most sensitive line available, look no further.

Rio Extreme Indicator
Rio Euro Nymph Rio LightLine Rio Gold Rio Grand
  Indicator Euro Nymph Lightline Gold Grand
The Rio Indicator can be used for nymphing with indicators, high sticking, and dead drifts. It has a long back taper for rollcasting and spey casts. The Duo-tone tip acts as an indicator when High sticking or Czech Nymphing. RIO's Technical Euro Nymph line has all the assets for the modern nymph angler. Built on a monofilament core that creates a stiff, slick line for quick feeding and less line sag between the rod guides, and an ultra-thin diameter to maximize sensitivity, and for lightning-fast hook sets. In addition, the core extends past the front end of the line to become a leader—resulting in no knots to get caught in the guides. The level line can be cut to length (from the back), allowing anglers to tune the line to the perfect length. The leader is .013" in diameter, pink to be easily seen, and is level, so can also be cut and tuned for varying situations. RIO’s LightLine has been designed to load slower, more traditional action fly rods such as bamboo, glass and the more “Classic” flexing graphite rods. Built to precisely match the industry line standards, this line will not overload such rods – even at longer range. The weight distribution and short front taper ensures the line loads at close range, making it ideal for fishing on smaller creeks and streams, while the softer, supple coating ensures the line remains relaxed and easy to handle in the majority of conditions. The RIO Gold has a special taper design that gives incredible loop stability at distance, a unique profile that allows a rod to load at close range and a front taper that delivers perfect presentation of flies between sizes #22 and #2. The RIO Gold is the ultimate all round, floating line for the trout fly fisher. The RIO Grand is a full line size heavier than the industry standard, and features more weight distributed towards the front of the line to easily load faster action fly rods. The line has a short head that is easy to cast, making it the perfect choice for fast action rods, or for more novice casters that like a little extra load to help them with the cast. The RIO Grand is built with "MaxCast" Technology, RIO's ultra-sophisticated line coating that actively repels water for higher flotation, longer casts and greater durability.
