This fly is an adaptation of the Bushys Grey. Again a truely great dun pattern. Working it in rivers and lakes can produce great results. Rust duns appear everywhere particularly on dark stony coloured river bottoms. We have also found that this dun in #10 can be fished effectively in lakes that produce the commonly known March Brown Mayfly. Again our large size range tells you how important it is to your success. See more in our news page: Best Flies Australia, Best Flies New Zealand
