AI picks by need

For fluorocarbon tippet for nymphs

Trouthunter Fluorocarbon Tippet (line)

Fluorocarbon sinks and is abrasion resistant, which suits nymphs and wary fish.

Not for: Dry-fly anglers, since fluorocarbon can pull small dries under.

For tapered trout leaders

Scientific Anglers Absolute (line)

Well-tapered knotless leaders that turn over flies cleanly on standard trout rods.

Not for: Anglers who only need tippet spools to rebuild existing leaders.

What the AI looks for in Fly Fishing Leaders & Tippet Materials

X sizing
X rating = 11 minus diameter in thousandths of an inch (0X is .011 in, 5X is .006 in). Diameter, not breaking strength, is what matches tippet to fly size.
Fly-to-tippet match
Rough guide: hook size divided by 3 gives tippet X size (size 15 fly, about 5X). Too heavy a tippet makes the fly drag or hinge; too light breaks off and twists.
Material
Nylon for dry flies; fluorocarbon for nymphs, streamers and clear water. Nylon floats and stretches; fluorocarbon sinks, is less visible and resists abrasion.
Leader length
About 7.5 to 9 ft for most trout fishing; longer for spooky fish on flat water. Length controls turnover and how close the fly line lands to fish.
Step-down
Attach tippet no more than one to two X sizes lighter than the leader's tip. Large diameter jumps weaken knots and spoil turnover.

Brands that matter

  • Rio: Broad leader and tippet range in nylon and fluorocarbon.
  • Scientific Anglers: Fly line maker with well-regarded tapered leaders.
  • Trouthunter: Popular for tippet with half-X sizes.
  • Umpqua: Long-running leader and tippet brand.
  • Seaguar: Fluorocarbon specialist whose lines are used as tippet.

What to avoid

  • Choosing tippet by breaking strength alone instead of X diameter.
  • Using old nylon tippet kept in sunlight or heat, which weakens it.
  • Fluorocarbon tippet on small dry flies.

Questions

Leader or tippet: what's the difference?

A leader is a tapered section linking fly line to fly; tippet is level line added to the leader's end so you can change flies without shortening the taper.

Can I tie fluorocarbon tippet to a nylon leader?

Yes, it is common; use a good knot such as a double surgeon's and keep the diameters close.
