Lines and leaders for put and take
The line is your direct contact with the fish, and more often than people think the weakest link. For put and take you only need to keep three things straight: the main line on the reel, the leader next to the bait, and for fly fishing the special fly line.
Main line, leader and fly line
Two sorts dominate. Monofilament is cheap, a bit stretchy and forgiving — a good all-round choice for spin and bait. Braid is thin and stretch-free with high feel, so you feel even small takes, but it is usually paired with a leader. Pick thin line for ordinary stocked fish and only step up if the water is known for really large fish. Unnecessarily heavy line scares shy fish and spoils the cast.
Next to the bait you want a fluorocarbon leader — less visible and it protects the main line against abrasion. Fly fishing uses its own line: the thick, weight-carrying fly line loads the rod, and a thin tippet sits next to the fly. Class must match rod and reel.
Line wears most next to the bait. Get used to clipping and retying, especially after a landed fish. Learn a couple of reliable knots and always wet them. Whole range: tackle.
FAQ
Which line should I use for put and take?
Thin monofilament or braid as main line, preferably with a fluorocarbon leader in clear water. Match the diameter to the fish — finer for ordinary fish, heavier if the water gives large fish.
Do I need a leader?
A fluorocarbon leader is less visible and good protection next to the bait, especially in clear water and on shy fish. It also spares the main line against abrasion.
How often should I change line?
Clip and retie next to the bait often, especially after a fish, because that is where the line wears most. The whole main line needs changing less often, when it feels rough or has memory.
