Fly Rods

Fly rods normally vary between 6 ft and 13 ft in length. Fly rods and lines are designated as to their "weight", typically written as Nwt where 'N' is the number (e.g. 8wt, 9wt, 10wt).

Rods are matched to the line according to weight. The rod's manufacturer will mark on the rod the fly line weights for which a rod has been designed. One-weight (1wt) rods and lines are the lightest; the weight designations increase up to the heaviest readily available rods and lines at 16-weight (16wt).[1] In general, 1wt through 2wt would be in the class used for small trout, and panfish, 3wt and 4wt are popular for small-stream fishing, 5wt is often considered the all-around rod for trout, 6wt and 7wt are used on large rivers and for fishing with streamers, 8wt to 9wt rods and lines might be used for steelhead or salmon in medium rivers, as well as for bass fishing with large flies and as lightweight salt water use, and 10-11wt rods and lines would be used for pursuing large salt water gamefish under conditions of high wind or surf. The heaviest rods (12–16wt) are mostly used for bluewater species (billfish, tuna) while fishing from a boat. The characteristics of these rods reflect the fact that only short casts are needed during this type of fly fishing, while lifting ability is at a premium.

The species pursued, under which conditions, will largely determine the weight of rod selected. Next, it is important to match the line to the weight of the rod. Using too heavy a line on too light on a rod, or vice versa, will dramatically affect casting performance. It may also permanently warp the rod blank. As a rule of thumb, you can safely go one line weight more or less (i.e. using an 8wt or 10wt line on a 9wt rod). There are also rods stamped with a range of weights. For example, a rod may be rated 7-8wt. This indicates the rod is designed for either a 7 or 8 weight fly line. There are also some rods rated for wider ranges (e.g. 8-9-10wt). The drawback to multi-rated rods is that compromises in flexibility or action are made in order to accommodate a wider range of line weights. For example, a rod rated for 8-9 weight line will be slightly stiffer than a straight 8wt but slightly softer than a straight 9wt rod.

Saltwater fly rods are built to handle powerful fish and to cast large, bulky flies over longer distances or into strong winds. Saltwater fly rods are normally fitted with heavier, corrosion-resistant fittings. The reel seat may also be equipped with a short extension often called a "fighting butt". Rods for saltwater fishing fall into the 8 to 15 weight class, with 12-weight being typical for most larger species like tuna, dorado (mahi-mahi) and wahoo (ono).
