Troutline Tactical BH PO Spotted Pheasant Tail Nymph is efficient for grayling fishing if is used in cold waters with dark colored rocks and stones. The dark brown body of nymph combined with the purple/blue spectra dubbing and hot orange hot spot provides a very good contrast in water. Non colored tungsten beads will help the fly to sink fast and will not scary the shy fish.
We had great results with this fly in Lapland and we consider it a must have fly for cold periods in fishing season when grayling is not so active.
