Adam Kerr –
Fished this fly on a steelhead run in the mountains. The stinger hooks caught a few fish that would have missed with standard flies. It sank well and stayed on the line during strikes. Good for both sink-tip and dry presentations.
Olivia Bond –
Used it during a cold-water steelhead season. The fly held up well in current and the hook held firm when fish took it. A bit more expensive than basic flies, but worth it for the performance.
Steven Randall –
Caught two steelhead in a single day with this fly. The stinger design gave a strong hold during the take. Works well both on dry and sink-tip lines. Reliable in fast-moving water.
