25 to 48 of 134 rigs
A 10-foot tarpon leader built the classic way: a 48" butt of 60 lb mono (.032"), 30" of 40 lb mono (.024"), a 30" 16 lb class tippet (.016") and a 12" bite tippet of 60 lb fluorocarbon (.028"). Albright knots join the class tippet to the heavier line on both sides, and a non-slip loop knot ties on the fly so it swims freely.
A heavy, modular leader for nymphs and streamers, built from RIO Powerflex: 72" of 30 lb (.017"), a 4 mm heavy tippet ring, 36" of 20 lb (.013"), a second 4 mm ring, and 36" of 10 lb 2X (.009") tippet, for 12' in all. The rings let you change tippets without shortening the leader, and the stout pieces turn over weighted flies.
A heavier do-it-yourself saltwater leader: 36" of 40 lb fluorocarbon, 24" of 30 lb, and a 24" tip of 20 lb, for 7' in all. It is short and stout so it turns over bulky flies in wind and stands up to hard-running fish, rough mouths and structure. The fly goes on with a non-slip loop knot so it swims freely.
A 9-foot leader built to turn over and hit a target, the way tournament accuracy and distance casting demand. It runs 44 inches of .024 inch mono, 28 inches of .020, 17 inches of .017 and 8 inches of .015 to an 11 inch tip of .012 inch, with most of its weight in the long butt. It straightens fully at the end of the cast and drops the fly where it was aimed.
A 9 foot 2 inch dry fly leader that ends in 4X and is built to land a fly with a little slack for drag-free drifts. It starts with 20 inches of 15 lb and 20 inches of 12 lb Maxima Chameleon, steps through 8 inches of 8 lb Maxima and 8 inches of 8 lb Stren Gold, then 12 inches each of 2X, 3X and 4X, and finishes with an 18 inch 4X tippet. Every join is a triple surgeon's knot.
A 9-foot all-fluorocarbon bonefish leader built to turn over shrimp and crab flies in the wind that blows across most flats. It runs 48 inches of 50 lb, 24 inches of 30 lb and 12 inches of 25 lb to a 24 inch tippet of 15 lb. The heavy butt carries the cast, and the 15 lb tip is strong enough to stand up to coral, mangrove roots and a bonefish's first run.
A 9.5-foot trout leader with a heavy butt, built to turn over big, wind-resistant dries on 5-7 wt rods. Nearly half its length is a 48 inch .026 inch butt, which then steps through 18 inches of .019, 10 of .017, 8 of .015, 6 of .013 and 6 of 1X (.010 inch) to an 18 inch 3X tippet. It pushes hoppers, stoneflies and big attractors out in the wind and lays them down straight.
An 8-foot (96 inch) three-piece dry fly leader built from the 25-15-10 formula: 36 inches of 25 lb mono, 36 inches of 15 lb and 24 inches of 10 lb. It is quick to tie from three spools and turns over big, wind-resistant dries such as hoppers, stoneflies, large foam flies and bass bugs.
A simple 7.5-foot (91 inch) saltwater leader for 8-9 wt rods, tied from three pieces of fluorocarbon: 39 inches of .024, 26 inches of .019 and 26 inches of .014. It turns over weighted shrimp, crab and baitfish patterns in wind, and the fluorocarbon sinks and stands up to abrasion. It is quick to tie on a boat or beach.
A 6.5-foot (77 inch) stillwater leader for sinking and intermediate lines on a 4-6 wt. It steps from 29 inches of 0X through 20 inches of 1X and 16 inches of 2X to 12 inches of 3X, a short, gentle taper that sinks with the line. The fly fishes at the depth the line sets, which is the point of a sinking line.
A 20-foot euro nymphing leader that fishes tight-line with mono, not fly line, outside the rod tip. It runs from 160" of 20 lb (.017") Maxima Chameleon into 18" of 15 lb (.015") Chameleon, 8" of 0X (.011") Seaguar Gold Label, a 24" .010" sighter and 30" of 4X (.007") fluorocarbon tippet. A size 14 tungsten jig nymph carries the weight.
A 12.5-foot tarpon leader for an 11-12 wt. It runs 72 inches of 60 lb mono, 48 inches of 40 lb mono and an 18 inch class tippet of 16 lb, ending in a 12 inch bite tippet of 50 lb fluorocarbon. The heavy butt turns over big tarpon flies, the class tippet sets the breaking strength, and the bite tippet takes the wear of a tarpon's rough jaw.
An 11-foot redfish leader for an 8-10 wt. It starts with 46 inches of .033" mono and steps down through 23 inches of .028", 23 inches of .026" and 17 inches of .024" to a 23 inch tippet of .016" fluorocarbon. The stiff butt turns over weighted shrimp and crab patterns, and the long fluorocarbon tip lands quietly and stands up to oyster shell and grass on shallow flats.
An 11-foot leader built on the half-again formula: each section is half the length of the one above it. It runs 60 inches of 30 lb mono, 30 inches of 20 lb and 15 inches of 15 lb, then a 27 inch tippet of 12 lb. The long, heavy butt carries the cast's energy down to the fly, so it turns over weighted and wind-resistant flies for flats and warm-water fishing.
An 11.5-foot tarpon leader for a 12 wt, all fluorocarbon. A 60 inch butt of 60 lb steps to 12 inches of 40 lb and 24 inches of 30 lb, then an 18 inch class tippet of 20 lb and a 24 inch bite tippet of 50 lb. The stepped butt turns over big tarpon flies on a 12 wt line, the class tippet sets the breaking strength, and the bite tippet stands up to a big tarpon's rough mouth.
A 10.5-foot mono stillwater leader built for an intermediate sinking line. It steps from a 43 inch butt of .011" down through 35 inches of .010" and 28 inches of .009" to a 20 inch tippet of 3X, .008", joined with triple surgeon's knots. The length keeps the fly line's splash away from the fly, and the slow-sinking line carries the fly down to cruising trout.
A wet fly team leader for swinging three flies at once. It starts with 72" of tapered leader cut back to 3X, then 4X Maxima Chameleon in 6", 18" and 24" sections joined with triple surgeon's knots. Two 4" tags off those knots hold the droppers, and the point fly ties to the end. The team covers three depths on every swing.
A thin mono euro nymphing rig: 144" of .012" Maxima Chameleon as a butt, 36" of Sunset Amnesia as a transition, and an 18" Cortland sighter, all 10 lb and joined with blood knots. A 2 mm tippet ring below the sighter holds 36" of 5X fluorocarbon tippet to a tungsten jig nymph. The thin butt sags less than a fly line and casts weighted flies with little effort, so contact with the fly stays direct.
A 30" streamer leader for trout on a sinking line or sink tip. It is two pieces: 12" of RIO Powerflex 0X (15 lb, .011") as a butt, joined with a triple surgeon's knot to 18" of 6 lb Drennan fluorocarbon. Kept short so the fly stays down where the line takes it.
A 7-foot bass bug leader after Steve Rajeff's formula: five sections of mono stepping from a .028" butt to a .014" tippet, joined with blood knots. The long, heavy butt and short taper carry wind-resistant poppers and hair bugs and turn them over on a 6-8 wt line. It is built for casting bugs tight to cover, not for delicacy.
A mono rig for fine, tight-line nymphing in clear water. A 72 inch RIO Powerflex butt runs to a 4 mm tippet ring, then 216 inches of .011 Sunset Amnesia and a 36 inch Cortland bi-color sighter to a second 4 mm ring. Below it, 72 inches of 6X RIO Fluoroflex Strong carries a small tungsten nymph. There is no indicator and no shot: the fly carries the weight.
A mono rig built to fish a weighted streamer on a tight line: 288 inches of 20 lb Maxima Chameleon, 24 inches of 12 lb Maxima HV, 12 inches of 12 lb red sighter mono and 12 inches of 2X Gold Label with a Backing Barrel marker, to a 4 mm tippet ring. Below the ring are 36 and 24 inch pieces of 2X fluorocarbon to a size 8 tungsten jig streamer.
A mono rig set up to fish a dry fly: 288 inches of 20 lb Maxima Chameleon, 24 inches of 12 lb Maxima HV, 12 inches of 12 lb red sighter mono and 12 inches of 2X Gold Label with a Backing Barrel marker, to a 4 mm tippet ring. Below the ring a short dry-fly taper runs 10 inches of 2X, 6 inches of 3X and 20 inches of 4X to the fly. It lets a nymph angler fish a dry without changing to a fly line leader.
A micro-thin mono rig for tight-line nymphing: 312 inches of .008 Maxima Chameleon, a 20 inch RIO two-tone sighter, and 48 inches of 5X fluorocarbon tippet to a tungsten jig nymph. The thin butt sags less than heavier mono, so a light fly stays in contact farther from the rod tip. The weighted fly does the work, with no indicator and no split shot.
