Best Fly Lines for Beginners

A fly rod does not cast a fly. It casts a line, and the fly goes along for the ride. That one fact is why a good line on a cheap rod outperforms a cheap line on a good rod, and almost nobody explains it to beginners.

The Frequency Trout is built on an Infinity-style belly taper with slightly longer front and rear tapers and a quarter-size-heavy profile. In plain terms: there is a little more mass than the nominal weight, which loads a rod with less line out of the tip. If you are new and your loop is collapsing because you cannot feel the rod bend, that extra quarter size is the most direct fix available.

The WF-5-F has a 34-foot head, 85 feet of total length and a 140-grain head weight on a braided multifilament core, with AST slickness treatment and welded loops at both ends. The welded front loop matters practically: you can loop-to-loop a new leader on in ten seconds, rather than learning a nail knot in the rain.

RIO Mainstream is the line we point at when someone asks what the cheapest line worth buying is. It is a weight-forward floating trout line from one of the two companies that define the category, and it is what Redington ships on Crosswater outfits — which is the main reason that kit casts better than its price.

We can tell you less about its taper than about the Frequency Trout, because RIO publishes less detail on it. That is the honest situation, so we will not invent numbers. What we can say is that a Mainstream in good condition is not the thing holding your casting back.

A leader is the clear, tapered length between your fly line and your fly. It exists so the energy in the cast keeps traveling after the thick fly line stops, which is what makes the fly land ahead of the line instead of on top of it.

The Powerflex Trout does this with a long, powerful butt section that transfers energy and a soft, flexible tippet end that lets the fly settle. It is knotless, so there are no knots in the taper to collect weed. For a beginner on trout water, a 9-foot 5X is the single most useful size to own, with 4X for bigger flies and 6X for very flat water.

Expect to use them up. Every fly you tie on costs you an inch or two of the thin end, and once the tippet section is short the leader stops turning over properly. That is normal, and the fix is tippet, not a new leader every time.

Tippet is plain level line on a spool, and its job is to be the sacrificial end of your leader. You tie a length of it to the thin end of your tapered leader, and when it gets short from fly changes you add another length instead of buying another leader.

RIO's Powerflex is a co-polymer with a PTFE coating in light gray. It is supple, which lets a small dry fly sit and drift naturally rather than being dragged by a stiff tether. Two spools — 5X and 4X — cover almost all trout fishing a beginner will do.

One thing worth knowing: nylon and co-polymer tippet ages. UV and heat weaken it, so a spool that has spent two summers on a dashboard should be thrown away rather than trusted on a good fish.
