Ray Bergman's 12 foot leader for nymphs and wet flies. Eight 18 inch sections of mono step down from .021" at the butt to .006" (5X) at the tip, joined with blood knots in the butt and triple surgeon's knots through the 0X, 3X and 5X pieces. It is built for one fly on a 4 to 7 weight rod. There is also a 6X variation; see the questions below.
A 15-foot dry fly leader with a long, heavy butt: 84" of .017", 12" of .012", 36" of 2X, 36" of 4X and 12" of 5X. The stout butt carries the cast and turns over larger dries in wind, while the long finer sections still let the fly land softly. It is built for 3-5 wt rods on bigger water. There's also a 6X variation; see the questions below.
An 8-foot-8-inch dry-fly leader tapered from 30 lb butt to 2X tippet, built to turn over grasshopper imitations and other larger terrestrial patterns. The stout butt handles the weight and air resistance of bigger flies while the fine 2X tip provides the delicacy needed for drag-free presentation on selective trout.
A 9' 10" tapered dry fly leader for trout on a 5-6 wt rod. It runs from a stiff .022" butt of Maxima Clear down through four more Maxima steps, then RIO Powerflex at .010" and .008" to a 24" tip of 4X at .007". The even taper turns over dry flies from #12 to #16 and lays the long tippet down with a little slack for a natural drift.
A 15-foot tapered dry-fly leader built to turn over gracefully and land softly on the water. The long taper and gradual step-downs from .017" butt to .006" tip make it well-suited for 3-5 weight rods, working especially well with smaller dry flies where a delicate presentation matters. There's also a 6X variation; see the questions below.
A 12-foot mono leader for fishing wet flies on lakes with a floating line. It tapers in .002" steps from a 36 inch butt of .021" through nine sections to a 27 inch tippet of 5X, .006". The long, fine taper lands a small wet fly or soft hackle without a splash on calm water and lets it sink and hang the way trout see natural insects.
A 54-foot tight-line mono rig for fishing weighted streamers and jigs to steelhead and big trout. It runs 564 inches of 20 lb Sunset Amnesia, 18 inches of 15 lb and 18 inches of 12 lb Maxima, a 4 mm heavy tippet ring, a 12 inch Cortland bi-color sighter and 36 inches of 0X fluorocarbon tippet. The thin mono replaces the fly line through the guides, so the fly sinks fast and you stay in direct contact with it.
A thin, light mono rig for tight-line nymphing small streams: 480 inches of .009 Maxima Chameleon, 24 inches of white Cortland indicator mono, then an 18 inch Cortland bi-color sighter. A 2 mm tippet ring below the sighter holds 36 inches of 5X fluorocarbon to a tungsten jig nymph. The thin butt sags very little, so small, light flies stay in contact.
A tight-line mono rig for small streams: 480 inches of neon green Sunset Amnesia as the casting line, a 36 inch step of 1X Maxima Clear, then a 16 inch Cortland bi-color sighter. A 2 mm tippet ring below the sighter holds 36 inches of 5X fluorocarbon to a tungsten jig nymph. The weighted fly does the work, with no indicator and no split shot.
A long tight-line mono rig for euro nymphing small streams. It runs 480" of 12 lb Maxima Chameleon (.013"), 24" of 8 lb Maxima Clear, 12" of neon red Sufix and 12" of neon green Amnesia, then a 16" Cortland bi-color sighter, joined with blood knots. A 2 mm tippet ring below the sighter holds 36" of 5X fluorocarbon to a tungsten jig nymph. There is no indicator or split shot: the fly is the weight and the colored mono shows the take.
Lefty Kreh's simple 9-foot leader: about half butt, a quarter middle, and the rest a short step and tippet. Here that is 48 inches of .024 mono, 24 inches of .021, 12 inches of .018 and 24 inches of .013 at the fly, joined by three blood knots. Built for a 7-8 wt line, it turns over streamers, bass bugs and light saltwater flies.
A short, stiff 7-foot (84 inch) leader for 4-7 wt lines. It steps from an 11 inch .021 butt through .019, .017, .015, .013, .011 and .009 to 16 inches of 3X at .008. The heavy butt and short length turn over bushy dries, hoppers, small streamers and other wind-resistant flies with accuracy.
A George Harvey dry fly leader, 11 feet long, built in 7 sections of Maxima. It runs from a .015" butt down to 30 inches of .006" (5X) tippet. Harvey designed the long, soft tip to land in slack curves rather than straight, so a single dry fly drifts naturally without drag. It is made for selective trout rising to small dry flies. A 4X variation is covered in the questions below.
Ray Bergman's 8 foot nymph leader. Six 16 inch sections of mono taper from .017" at the butt to .006" (5X) at the tip, with blood knots in the butt and triple surgeon's knots through the 0X, 2X and 5X pieces. It is a short, controllable leader for one nymph on a 3 to 5 weight rod. There is also a 4X variation; see the questions below.
A 9 foot 2 inch leader for emergers and wet flies that tapers from a .017 inch butt in six sections to a 30 inch 4X (.007 inch) tippet. The even steps turn the fly over on 3-5 wt rods, and the long tippet lets an emerger ride in the surface film or a wet fly sink and swing without drag.
A 24-foot nymphing leader for fishing tight-line on a 3-5 wt. It runs 112" of .016" butt, 35" each of .014" and .012", a 35" 1X (.010") sighter, 20" of 4X (.007") and 48" of 5X (.006") tippet to a size 16 tungsten-bead nymph. The long leader keeps the heavy fly line out of the drift, so the nymph sinks and drifts with little drag.
