LeechWinkler's Balanced Leather Leech
Winkler's Balanced Leather Leech, designed by Matt Winkler and demonstrated by Charlie Craven, represents an innovative approach to balanced fly construction. The pattern uses Ultrasuede (Leech Leather) to form an undulating tail that ripples and shimmies on both the sink and retrieve, creating irresistible movement that triggers strikes from stillwater trout.

Overview
This Charlie Craven tutorial demonstrates Matt Winkler's innovative design that builds on Jerry McBride's original balanced fly technique. The key innovation is using Ultrasuede (which Winkler dyes and sells as Leech Leather) for the tail, creating movement unlike traditional materials. The slim Simi Seal body provides just enough flash and movement to complement the tail without overwhelming it.

Fishing Tips
Season
Year-round stillwater effectiveness with the Leech Leather tail providing movement even in cold water conditions when natural materials might become stiff.
Presentation
Fish under an indicator allowing the fly to hang horizontally in the water column. The balanced design combined with the Leech Leather tail creates natural movement even when stationary.
When to Use
Select this pattern when fishing stillwater under indicators where the balanced presentation provides an advantage. Particularly effective when trout are cruising and inspecting flies before committing.
Water Type
Designed specifically for stillwater fishing. The balanced design and Leech Leather tail excel in lakes and ponds where flies are presented under indicators.
Rigging Suggestions
Fish on 12-15 foot leader with 5X-6X fluorocarbon tippet under an adjustable indicator. The tungsten bead provides adequate weight for proper balance and sink rate.
Visibility & Floatation
The peacock green Simi Seal body provides subtle flash while the olive Leech Leather tail creates natural movement. The copper bead adds weight while complementing the overall olive/brown color scheme.
