The D&D Cripple series of flies have been hot flies for us and our customers. The D&D Cripple PMD keeps that trend going strong. Fish the D&D Cripple PMD during early to mid-summer months on your favorite trout river. The D&D Cripple PMD sits half in and half out of the water like the emerging mayfly duns. The CDC feather and hackle in the front of the fly keeps it floating and easy to see for the angler.
