Randomly selected: Schweitzer's Dry, Windy Conditions

Category: Dry Fly Leaders
This leader is made to turn over a dry fly a bit easier in windy conditions while still allowing for enough slack for floating a dry fly in tricky currents.
Add more tippet to accommodate a longer drift pattern (similar to Harvey slack).
