Geggjuð intruder fluga með þungum dumbell augum í sjóbirtinginn en hún var upphaflega hönnuð af snillingnum Rob Crandall fyrir Steelhead veiðar.
Þetta hefur Rob Crandall að segja um þessa flugu:
This fly I had the hardest time turning over to the commercial side. It is an all time best producer for me and it is hard to beat for both winter, spring, summer and fall fish. Black and red are great colors for steelies.
Rob Crandall lives in Portland, Oregon, where he operates Water Time Outfitters, which offers guided fishing trips on the Deschutes River for trout and steelhead, as well as guided fly fishing for steelhead on the Clackamas, NF Nehalem, Trask and Oregon Coast rivers in the winter.
