Straggle Leeches are great searching patterns. Brian's Straggle can represent both leeches and damselfly nymphs, depending on the color.
Tied on a 60° jig hook with tungsten beads allows the patterns to sit on a slight horizontal angle. You can also attach them using a clinch or improved clinch knot to encourage the pattern to sit horizontally when suspended under a Quick Release Indicator.
The various bead colors provide a little extra flash to these proven stillwater patterns. Fish Brian's Straggle Leech under an indicator or cast and retrieve on various sinking line densities.
