Brandon Howard –
This fly looks exactly like a real stonefly nymph. I’ve used it on the Bow River and caught several trout. The rubber legs move naturally in the water, which makes a big difference in presentation.
Joe Davies –
Highly recommended for anyone fishing freestone streams. The detail on the back plates and tail is impressive. It’s a go-to pattern when targeting nymphs in clear water.
Stephanie Martin –
Good quality and realistic. A bit harder to tie than expected, but once on the water, it performs well. Works well in moderate current conditions.
Grace Morrison –
Used it during a morning drift on the Bow River. Caught a brown trout within minutes. The movement of the legs really helps it stay natural in the water.
