FAQ
What makes this fly effective for picky trout?
The split wingcase mimics the natural emergence of a mayfly nymph, which is a key trigger for selective trout. The tungsten weight ensures a steady sink, allowing for precise presentation without the need for heavy split shot.
Is this fly suitable for use in still or moving water?
This fly is best suited for tailwaters and slow-moving streams where trout are more selective and attentive to subtle imitations like emerging nymphs.
Can I use this fly in different seasons?
Yes, this fly is ideal during the mayfly hatches when nymphs are emerging, typically in spring and early summer.

This fly performs exactly as described. The split case is noticeable and the tungsten weight keeps it sinking steadily. I’ve used it in a tailwater stream and got several strikes from picky trout that ignored other flies.

Great detail on the split wingcase. It’s hard to find a fly that looks so natural during emergence. The sink is smooth and doesn’t drag, which helps with accuracy in my casting.
Yvonne Edmunds –
Works well in slow-moving water. The trout seem to react to the split case, especially when the current is light. A bit heavier than expected, but that’s probably due to the tungsten core.

Used this during a morning hatch and caught two fish. The fly stayed on the bottom and looked realistic. It’s a solid addition to my nymph collection.
