How to attach a tapered leader

All Finner fly lines come with a welded loop, and all leaders include a perfection loop for easy connection. Follow these steps to attach your leader securely:

We will send you an email after your purchase, with video guides on how to attach leader and backing.

How to Attach a Leader Using a Perfection Loop

Step-by-Step Guide

- Hold the Fly Line Loop – Locate the welded loop at the end of your fly line.

- Thread the Leader Through the Fly Line Loop – Take the perfection loop at the end of your leader and pass it through the fly line loop.

- Feed the Leader Through Itself – Pull the leader butt section (thicker end) through its own loop.

- Gently Tighten the Connection – Pull both the fly line and leader ends to snug the loops together. Ensure the connection is secure but not overly tight to allow for easy changes.

This loop-to-loop connection creates a strong, seamless setup, allowing for quick leader changes without knots.

How to attach backing

To attach the backing to the fly line, we recommend using Finner braided loop connectors.

We will send you an email after your purchase, with video guides on how to attach leader and backing.

How to Attach Backing to a Fly Reel

Secure the reel and tie the backing to the spool using an arbor knot.

How to clean & maintain your fly line

To clean your fly line we recommend using Finner Fly Line Speed Boost

We will send you an email after your purchase, with video guides on how to maintain your fly line.

Before every fishing session apply Fly Line Speed Boost to the entire length of floating lines. Apply only to the running line on sinking lines. At the end of the season wipe the line with a damp cloth on the entire length then apply Fly Line Speed Boost.

What weight fly line should I get?

Match the line weight to the rod rating. For instance, if you have a 7 weight rod get a 7 weight line.

If the rod has 2 numbers on it (6/7 for instance) then match it with the heavier number, 7 in this case. If it's rated 7/8, get an 8 weight line and so on.

Choosing the right head length

- Short Heads: 3 x rod length
- Quick and compact
- Great for tight spaces
- Ideal for beginners

- Mid-Length Heads: 4 x rod length
- Best all-rounder,
- Provides a balance of control and distance

- Long Heads: 5-6 x rod length
- Offers longer, more stable casts
- Requires better technique and control
- Harder to cast, especially for beginners

Choosing the right taper

Short, Blunt Taper

- Big flies

Mid-Diameter Taper
- Balanced performance between power and finesse
- Versatile for varied fly sizes and conditions
- A great all-around choice for most anglers

Does what it should

Slick and straight. Very impressive line for the money. I have used more expensive lines in the past that kink and curl and will not straighten even after stretching. This line is a joy to use.
