Two of the most productive patterns ever, combined on one hook- an egg and a San Juan worm. The dry fly purists are picketing across the globe. This pattern is effective for trout, carp, and steelhead, throughout the year. Dead drift it under an indicator, or try a slow retrieve through the deep, slow pools. It is DEADLY on the stocked and wild trout streams from North Carolina to Michigan, Colorado to California! May the Force be with you. Orvis customers have given many great reviews.
