What are Fly Rod Actions?

Fly rods are some of the most intricately designed and engineered pieces of fly-fishing equipment—but also some of the most misunderstood. There are slow-action rods, fast-action rods, and rods that fall in between. But what do those actions mean, and what are the various benefits? Let's take a look at what fly rod action actually is, and the benefits of different types of fly rod actions.

What is Fly Rod Action?

Fly rod action refers to the way a fly rod bends and flexes when pressure is applied to it. The variations in action result in the differences in "stiffness" you'll feel between different rods, and there are three main types of fly rod actions: fast, medium, and slow. 

Fast Action Fly Rods

Fast action fly rods bend mainly in the tip section, making them ideal for long distance casting and reaching fast moving fish. Ideal in saltwater scenarios, fast-action rods are also great for windy conditions and casting heavier flies. However, fast action rods can be more difficult to control and may not be as suitable for beginners.

Over the years, manufacturers have produced faster and faster rods, resulting in fly line manufacturers creating slightly heavy lines to help load these rods. Most of the time, when fishing a fast-action rod, having a half-size heavy line (like the Scientific Anglers Amplitude Infinity) will help load the rod and generate more line speed.

Best Uses:

• Saltwater
• Throwing big flies
• Battling the wind 

Medium Action Fly Rods

Medium action fly rods bend in both the tip and the midsection, providing a good balance of distance and control. They are well suited for a variety of fishing situations, and are often considered the most versatile of the three action types.

Thanks to their ability to generate power, yet remain nimble, medium action fly rods are supremely popular in many models. This generally comes down to personal preference, as a medium-action fly rod can do just about anything a fast-action rod will do, but can be more forgiving on your cast. 

Best Uses:

• Trout
• Bass
• Saltwater

Slow Action Fly Rods

Slow action fly rods bend primarily in the lower section of the rod, providing more sensitivity and a softer feel. They are best for close-up casting and are great for beginners as they are the easiest to control. Slow action rods can also be used to fish in tight spaces like brush or trees.

Slower-action rods are best suited for dry fly fishing, but can be used anywhere. Fiberglass fly rods are a great example of a slow action, and they have been used all over the world to catch fish both large and small. While slow action rods excel on small fish and with smaller flies, your imagination is the limit when using a slower action rod. 

Best Uses

• Beginners
• Dry Flies
• Tight cover
