How to tell when your line needs changing
Read the three signs that line is spent — a curl that won't come out, a rough feel, and lost distance — before it takes a fish with it.

What this skill is for
Line is the cheapest part of the rig and the one that does all the failing. Abrasion, sunlight and memory quietly eat its strength long before it breaks, and the section nearest the tip takes the worst of it.
What you need
- A soft cloth
- Your fingers and eyes
- A note of when you last spooled
Step by step
- 01
Pull it through a cloth and feel it
Pinch the line through a soft cloth and draw it through your fingers. Rough, fuzzy or chalky patches are abraded sections; cut them out and retie, or change the line if there are many.
- 02
Look for permanent curl
Monofilament and fluorocarbon lose their memory resistance with age. If the line holds a coil on the water even after a dozen casts, it's tired and it will cast badly and detect bites poorly.
- 03
Check the first few metres most
That section has touched rocks, weeds, tree bark, boots and the water's surface film more than anything else on the spool. Re-clip the end regularly and shorten it when it feels rough.
- 04
Watch your casting distance
A steady drop in distance with the same lure and the same rod is usually worn line, not a change in form.
- 05
Change it after abuse
A hard fight over rocks, a long drag through weed or a snag that you pulled free all cost the line. Shorten it, and consider re-spooling if it was a serious scrape.
- 06
Keep a rough date
Write the month in the spool or in your notes. A line that's a season old, stored in the sun and used weekly is not the line you spooled.
Where it goes wrong
- Waiting for a break to tell you the line was worn.
- Assuming braid is immune — it frays and loses strength where it's abraded.
- Leaving old line buried under fresh top-shots for years.
- Storing a spooled reel in the sun.
