Fishing lines, decoded.
Line is the only tackle connected to the fish the entire time - and the wall of spools reduces to 8 genuinely different types once you know what each is FOR. Full profiles below, and a straight which-line-where matrix to settle the eternal question. Knots to join them live in the knot guides.
🧭 Which line, where The short answer for every situation.
| Situation | Reach for | Why |
|---|---|---|
| First spool / all-round spinning | Braid + fluoro leaderor plain mono | Thin braid casts and lasts; the leader adds stealth. Mono alone is fine while learning. |
| Crankbaits & trebled lures | Monofilamentor copolymer | Stretch cushions trebles so hooks stay pinned. |
| Topwater | Mono / braidnever fluoro | Both float; fluoro sinks and drowns the lure's nose. |
| Clear water, pressured fish | Fluorocarbonfull spool or leader | Closest thing to invisible; sinks into the strike zone. |
| Heavy grass & frogs | Straight braid40-65 lb | Cuts weeds, no stretch for hooksets in slop. |
| Trolling | Monoor lead core for depth | Stretch absorbs strikes at speed; colors count depth. |
| Pike, musky & toothy salt | Wire leaderover any main line | Teeth shear everything else - wire is the rule. |
| Float / ledger coarse fishing | Copolymer / monosupple, forgiving | Easy handling, gentle on light hooklinks. |
| Fly fishing | Fly line + leader + tippetmatched to rod weight | The line is the casting weight - see it decoded. |
| Deep vertical jigging | Braid + fluoro leaderthin diameters | Zero stretch = you feel bottom and bites 30 m down. |
🧵 Main lines What fills the spool - mono, fluoro, braid and the blends.
🎗️ Leaders & bite protection The last meter the fish actually inspects - and the wire that survives teeth.

Line is only as strong as its knot
Every line type has knots it loves and knots that betray it - the knot guides and knot-strength notes pair each line with connections that hold, and the rig catalog puts it all to work.
