Cameron White –
Used this fly during a high-water season and caught several trout in a single day. The action and color match the natural worm perfectly, especially in murky water. A reliable choice when other patterns don’t work.
Oliver Rees –
Fished in a tailwater stream with poor visibility and this pattern worked consistently. Fish took it on the first cast. Good for runoff conditions when other flies fall flat.
Melanie Ferguson –
This is one of my go-to flies for off-color water. The tan color blends well and the body shape looks realistic. I’ve used it in multiple seasons and it continues to perform well.
