Rigs Lab · Gear & fly fishing rigs + leaders
The rig builder and library for fishing. Lay out every cut, knot and turn to scale, start from a photo of a formula in a book, on a website or in your notebook, then publish it for anglers everywhere to tie, clone, share, print and fish.
Build it to scale
Every section, knot and turn, drawn the way you tie it, with the cut list worked out for you.
Start from a photo
Snap a formula from a book, a website or your notebook and it comes back as a rig you can edit.
Test it in the tank
Watch it drift, sink and turn over before it ever touches the water.
Share it, print it

I built this rig to get a weighted hex fly down to the lake bottom where trout are waiting for natural hex emergers to rise up the water column. It uses a slip bobber to suspend the fly 12 to 24 inches above the bottom in 15 to 35 feet of water, letting me fish without casting while the fish camp in place before they start moving up to chase the hatch.
A 5' 6" (66 inch) all-fluorocarbon leader for fishing small chironomids and nymphs on a sinking or intermediate line in clear lakes. It runs 18 inches of 20 lb Seaguar Blue Label (.016"), 24 inches of 10 lb fluoro (.011"), a #12 barrel swivel and 24 inches of 5X (.006") fluoro tippet. A short leader lets the line set the depth, and the finer tippet helps with wary fish.
A 5' 6" (66 inch) all-fluorocarbon leader for fishing chironomids and small nymphs on a sinking or intermediate line in lakes. It runs 18 inches of 20 lb Seaguar Blue Label (.016"), 24 inches of 10 lb fluoro (.011"), a #12 barrel swivel and 24 inches of 4X (.007") fluoro tippet. A short leader lets the line set the depth, so the fly fishes right where the line tip is.
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 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.
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.

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.
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 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.

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 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.
An 8-foot leader built on a smooth, gradual taper from .018" butt to .006" tip. It's designed for light-touch presentations to panfish in still water, where a gentle cast and a forgiving taper help you land small flies without breaking off. There's also a 4X 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.
