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.
A 17-foot leader for nymphing under an indicator at short range on a 3-5 wt. It steps down in 29" sections from .018" through .016", .014" and .012" to 1X (.010"), then a 23" 3X (.008") sighter and 40" of 5X (.006") tippet. A 1/2" trapped-air indicator rides on the 1X section, and a No. 4 split shot sits 10" above a size 16 bead-head nymph.
A 9-foot wet fly leader that steps down from a .019 inch butt in seven sections to 18 inches of 5X (.006 inch) tippet. The even taper turns over soft hackles and small traditional wet flies on 3-5 wt rods and lets them swing and drift with life in the current.
A 13-foot euro nymphing leader that loops to the fly line and fishes small, weighted nymphs on a tight line. It runs from 74" of .016" butt into 33" of .014" Sufix Elite, a 12" .011" transition, a 16" 3X (.008") sighter and 22" of 5X (.006") tippet. The fine tippet lets a size 16 tungsten nymph sink fast and drift naturally.
A 10' 5" nymphing leader built on the 60/20/20 idea: a long, stiff butt, a short taper and a fine tip. About 60 percent is butt, 49" of 30 lb and 25" of 20 lb Maxima Chameleon, 74" in all. About 20 percent is the taper, 12" each of .015" and .010" Maxima Ultragreen, 24" in all. The last 20 percent or so is the tip, 12" of 2X at .009" and 15" of 4X at .007", 27" in all. It turns over a single tungsten bead nymph and keeps contact with it in the drift.
A 26-foot mono nymphing leader for big trout in runs and pockets, fished tight-line with no indicator. A long .014" butt steps through .012" to a 1X sighter, then 36" of 3X fluorocarbon to a tungsten jig stonefly. The heavy fly does the sinking and the sighter shows the take, so the drift stays direct from rod tip to fly.
A straightforward 8 foot 5 inch streamer leader for 4-7 wt rods. It tapers from a .021 inch butt through four 15 inch sections, then 9 inches of .013 inch and 8 inches of 0X, to 24 inches of 2X tippet. The stout tip turns over buggers, sculpins and baitfish patterns and stands up to hard strips and strip-sets on trout.
A simple 25-foot euro nymphing leader: 211" of level .012" mono, a 42" 1X (.010") sighter and 42" of 5X (.006") fluorocarbon tippet. The thin level butt sags less than a heavy taper, so the line stays straight to a size 16 tungsten-bead nymph and small takes show on the sighter.
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.
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 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 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.
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.
