A 5-foot leader for sink-tip lines: 36" of 20 lb fluorocarbon joined with a triple surgeon's knot to 24" of 10 lb fluorocarbon. Short and dense, it keeps a streamer near the depth of the tip, with a little more distance from the line than a 4-foot leader for clearer water.
A 5-foot trout streamer leader for full sinking lines: 24" of 0X fluorocarbon at .011" joined with a triple surgeon's knot to 36" of 2X fluorocarbon at .009". Short and dense, it keeps a streamer down near the depth of the line for trout holding deep in lakes, pools and big runs.
A 4-foot leader for sink-tip lines: 24" of 20 lb fluorocarbon joined with a triple surgeon's knot to 24" of 10 lb fluorocarbon. Short and dense, it keeps a streamer down at the depth of the tip, for big trout and other fish holding deep in current.
A 4-foot fine tippet section to rebuild a dry fly leader that has been cut back to 3X. It steps 12" of 3X fluorocarbon to 12" of 4X, then 24" of 6X at .005" to the fly, joined with triple surgeon's knots. It is for small dries and midges over selective trout on slow, clear water.
A 4-foot tippet section to rebuild a dry fly leader that has been cut back to 2X. It steps 12" of 2X fluorocarbon to 12" of 3X, then 24" of 4X at .007" to the fly, joined with triple surgeon's knots. It restores a fine, supple tip without buying a new leader.
A 32-foot tight-line nymphing leader for 3-5 wt rods. It runs 288" of 20 lb Maxima Chameleon at .017", steps through Maxima HV and Sunset Amnesia at .013" and Seaguar Gold Label at .011", then a 1X sighter and 36" of 4X fluorocarbon to a tungsten bead perdigon. The thin butt hangs off the rod tip without sag, so the drift stays direct from rod to fly.
A 15.5-foot stillwater indicator rig for hanging a small chironomid near the bottom of a clear lake. An 18" butt of 20 lb Seaguar Blue Label leads into 120" of 10 lb (2X, .009") Blue Label, a #12 barrel swivel and 48" of 5X (.006") fluorocarbon to a size 16 tungsten-bead chironomid. A 7/8" release indicator rides near the top, and a No. 4 split shot sits just above the swivel.
A 15.5-foot stillwater indicator rig for hanging a chironomid near the bottom of a lake. An 18" butt of 20 lb Seaguar Blue Label leads into 120" of 10 lb (2X, .009") Blue Label, a #12 barrel swivel and 48" of 4X (.007") fluorocarbon to a size 14 tungsten-bead chironomid. A 7/8" release indicator rides near the top, and a No. 4 split shot sits just above the swivel.
A 9' 10" dry fly leader for light 3-4 wt rods. A 29" butt of .020" Maxima Clear steps down through .017", .015" and .012", then RIO Powerflex at .010", .008" and .007" to 5X at .006". The last two pieces, 8" and 22" of 5X, make a 30" tippet that lands small dries softly on quiet water.
A 10' 2" tapered trout leader that does a bit of everything on a 5-6 wt rod. A 48" butt of .022" Maxima Chameleon steps through .017", .015", .010" and .009" to a 14" tip of 4X at .007". It turns over a dry fly, a small nymph or a light streamer without a change of leader.
A three-piece streamer leader that steps from 30 lb to 20 lb to 10 lb Trilene Big Game, the 3-2-1 in its name. It runs 10 feet: a 72 inch butt, a 24 inch midsection and a 24 inch tippet, joined with triple surgeon's knots. Stiff, simple and quick to tie, it is built to turn over streamers and stand up to fish that grab hard.
A long mono rig for tight-line euro nymphing. A 144" butt of 20 lb Maxima Chameleon (.017") is blood-knotted to a 36" Sunset Amnesia sighter (12 lb), then an 18" transition of 12 lb Cortland mono (.013"). That runs to a 2 mm tippet ring, then 48" of 5X fluorocarbon (.006") to a #16 tungsten bead Perdigon. The thin mono butt lets you hold the line off the water and watch the sighter for strikes, and the weighted fly gets itself down without shot or an indicator.
A 10-foot wet fly leader for light 3-5 wt rods. It tapers evenly from a .019" butt through seven steps to a 22" tip of 5X at .006". The length and fine tip let a soft-hackle or wet fly sink and swing naturally on clear water.
A simple indicator nymphing leader, 12' 11" long, for a 5-6 wt line. It starts with a 22" butt of .012" mono and 79" of 0X mono, then steps down through 20" of 3X fluorocarbon to 22" of 5X fluorocarbon. Below that is a 2 mm tippet ring and a final 12" of 5X to the fly. A 1/2" trapped-air indicator rides on the 0X, and a BB split shot sits just above the ring to get the nymph down.
Gary Borger's dead-drift dry fly leader in three sections: a stiff .013" butt, a short .010" step and a long .007" tippet, or .006" (5X) for smaller flies. Quick to tie, quick to repair on the water, and it turns a dry fly over without fuss.
Pascal Cognard's 18-foot euro nymphing leader: a long, even taper from 18 inches of .018 mono through .016, .014, .012 and 1X to a 20 inch 3X sighter of Cortland bi-color indicator mono, an 8 inch step of 5X and 79 inches of 6X. It turns over a weighted nymph on a 3-5 wt rod and keeps the fly in direct contact, with no indicator and no split shot. There's also a 7X variation; see the questions below.
A 14-foot leader built for clear, calm lakes where trout can see far. The long, fine taper from .015" butt down to 5X (.006") lets you cast smaller flies with less disturbance and set the hook cleanly in stillwater. Use this when you need distance, stealth, and a natural presentation in lakes where the fish are selective. There's also a 6X variation; see the questions below.
An 18' 6" leader for fishing a single fly on a floating line in stillwater. It starts with a 30" butt of .017" and 28" of .013", then steps down through 1X, 2X, 3X and 4X sections to 82" of 5X (.006") tippet. The heavier butt carries the cast off a 4-6 wt line, and the long fine tip lets small flies land softly and sink naturally in calm water.
A 13.5-foot euro nymphing leader that loops to the fly line. It steps down evenly through 42" each of .016", .014" and .012" mono into an 18" 3X (.008") sighter and 18" of 5X (.006") tippet. The even taper turns over a weighted nymph softly, and the fine tippet lets a small tungsten fly sink fast.
George Harvey's 9-foot wet fly leader: a short 10" butt of .017", then five 20" sections of .015", .013", .011", .009" and .008" (3X), for 9' 2" in all. The even taper turns over a wet fly or soft hackle and lets it sink just under the surface and swing across the current. It is a simple, proven leader for a single wet fly on a floating line.
