A 15-foot dry-fly leader for flat, clear water and wary trout. A 72 inch RIO Powerflex butt runs to a 4 mm tippet ring, then 36 inches of .013 and 24 inches of 2X copolymer and a 12 inch step of 4X to a second 4 mm ring, with 36 inches of 5X RIO Suppleflex at the fly. The long, fine tip lets a small dry drift without drag.
George Harvey's 11.5-foot dry fly leader, finished in 5X. It starts with a soft .015" butt and steps down .002" at a time through four 18" sections (.015", .013", .011", .009"), then 15" of 3X, 15" of 4X and a long 36" tippet of 5X, for 11' 6" in all. The soft butt and long, fine tippet land the fly with slack so it floats drag-free over slow, clear water. It suits a 5 wt rod.
George Harvey's 10-foot dry fly leader, finished in 4X. It starts with a soft .015" butt and steps down .002" at a time through four 18" sections (.015", .013", .011", .009"), then 15" of 3X and a long 36" tippet of 4X, for 10' 3" in all. The soft butt and long tippet are meant to land the fly with slack in the tippet, so it floats drag-free over mixed currents. It suits a 5 wt rod.
Gary Borger's leader formula built as an all-round 9-foot trout leader: 51" of .020" butt, 13" of .013", 26" of 2X (.009") and an 18" tip of 4X (.007"). Borger's idea is a heavy butt that carries the cast and a quick step down to the tippet, so the leader turns over the fly with energy to spare. It suits dry flies and nymphs on 4-6 wt rods.
Gary Borger's 9-foot leader for bouncing a nymph along the bottom: 45" of .020" butt, 17" of .013", and a long 45" tippet of 0X (.011"). Two No. 4 split shot ride 10" above a size 8 stonefly nymph, and a small yarn indicator on the butt shows the take. The stout tippet holds up to the shot, snags and big fish on 4-7 wt rods.
Gary Borger's 7.5-foot leader for flies you move, finished in 3X: 51" of .020" butt, 13" of .013", and 26" of 3X (.008") tippet. The short, stout design keeps the line straight to the fly, so stripped and swung wet flies and nymphs stay under control and takes are felt. It casts well on 4-7 wt rods.
Gary Borger's 7.5-foot leader for flies you move: 51" of .020" butt, 13" of .013", and 26" of 2X (.009") tippet. The short, stout design keeps the line straight to the fly, so stripped and swung wet flies and nymphs stay under control and takes are felt. It casts well on 4-7 wt rods and turns over weighted flies.
Gary Borger's 10-foot dead-drift nymph leader, finished in 5X. It runs 51" of .020" butt, 13" of .013", 51" of 2X (.009") and a 6" tip of 5X (.006"), for 10' 1" in all. The long level 2X section lets a weighted nymph sink freely, and the finer tip suits small nymphs in clear, slow water on a 3-6 wt rod.
Gary Borger's 10-foot dead-drift nymph leader, finished in 4X. It runs 51" of .020" butt, 13" of .013", 51" of 2X (.009") and a 6" tip of 4X (.007"), for 10' 1" in all. The long level 2X section lets a weighted nymph sink freely instead of being pulled up by a taper, and the heavy butt still turns it over on a 3-6 wt rod.
A dry-dropper on a 9 foot tapered mono leader. It steps from 36 inches of .017" through .015", .013", 0X and 2X to 24 inches of 4X tippet tied to a size 10 to 14 foam or parachute dry. Off the dry's hook bend, 18 inches of 5X fluorocarbon hangs a size 16 to 22 bead-head nymph, so the whole rig runs about 10 and a half feet.
A 9 foot 6 inch carp leader for an 8 weight rod. It runs 48 inches of 30 lb Maxima Clear, then 24 inches of 20 lb, 12 inches of 15 lb and 6 inches of 12 lb Maxima Clear, ending in 24 inches of 0X fluorocarbon. The heavy butt turns over a weighted carp fly in wind, and the stout tip holds big fish around weeds and snags.
A 9 foot 6 inch carp leader for a 6 weight rod. It runs 48 inches of 20 lb Maxima Clear, then 24 inches of 15 lb, 12 inches of 12 lb and 6 inches of 8 lb (1X) Maxima Clear, ending in 24 inches of 2X fluorocarbon. The long, stout taper turns over a weighted carp fly and lays it down far enough from the fish to keep it calm.
A tight-line mono rig for small streams with a long, three-color sighter. It runs 480 inches of 20 lb Maxima Chameleon as the casting line, a 24 inch step of 12 lb Maxima Clear, then 12 inches of neon red Suffix and 12 inches of neon green Amnesia, a 4 mm tippet ring, and 12 inches of Cortland bi-color. A 2 mm tippet ring below the bi-color holds 36 inches of 5X fluorocarbon to a tungsten jig nymph.
A mono rig for small streams that fishes nymphs tight-line and small streamers on one leader. It runs 480 inches of 20 lb Maxima Chameleon as the casting line, a 24 inch step of 12 lb Maxima Clear, then a two-color sighter of 12 inches of neon red Suffix and 12 inches of neon green Amnesia. A 2 mm tippet ring below the sighter holds 36 inches of 4X fluorocarbon to a tungsten jig nymph.
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 5.5-foot steelhead leader with a heavy point: 28" of .026" mono joined with a double uni knot to 38" of .017" mono. Built for sink tips and Skagit heads on 7-9 wt rods, it keeps the fly near the depth of the tip and the thick point shrugs off rocks, wood and hard takes.
A 5.5-foot steelhead leader with a heavy point: 28" of .026" mono joined with a double uni knot to 38" of .016" mono. Built for sink tips and Skagit heads on 7-9 wt rods, it keeps the fly near the depth of the tip and the thick point shrugs off rocks, wood and hard takes.
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 steelhead leader for sink tips and Skagit heads: 12" of 20 lb Ande joined loop to loop with 36" of 10 lb Maxima Ultra Green. The short, stout build keeps the fly at the depth of the tip, and the loop join makes changing a frayed point quick on the river.
A 4-foot steelhead leader for sink tips: 12" of 15 lb Maxima joined with a triple surgeon's knot to 36" of 10 lb Maxima. It is short and stout so the sink tip sets the depth and the fly stays down in the swing.
A 4-foot saltwater leader for full sinking lines. It is 18" of 40 lb fluorocarbon, 12" of 30 lb and 18" of 20 lb, joined with triple surgeon's knots, with the fly on a non-slip loop knot. The short length keeps the streamer down at the depth the line reaches, for stripers, jacks and other fish feeding below the surface.
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.
