I’ve used this fly for several seasons now and it consistently catches trout in clear streams. The color and shape match the natural mayflies well. The hand-tied quality is evident and the hook holds up well after repeated use.
Charles Anderson –
Great imitation of PMD hatches. Works well in early summer when the trout are active. The three-pack is a good value for a classic pattern. A bit delicate when handling, but overall reliable.

This is the fly I’ve relied on for years. The Light Cahill is a proven pattern, and the 20-size hook is perfect for finesse fishing. I noticed no shedding or breakage after multiple casts.
