The Blue Assassin is hands-down one of the most effective midge mergers I've ever used, especially on tailwater such as the Chattahoochee Tailwater below Buford Dam or on the Toccoa.
     Developed by Chris Scalley of River Through Atlanta Guide Service, the Blue Assassin has given me many great days on Georgia's Chattahoochee and Toccoa rivers as well as on countless other streams across the eastern United States.  Yes, it's predominant hue is blue - not what you normally expect to see in a fly. But there is no arguing with the fact that it works really, really well.
     I usually tie the fly on size 18 hooks, but I recommend going with size 14 or 16 hooks while you learn.
     I think you'll enjoy tying and fishing the Blue Assassin. Meanwhile, if you see Chris Scalley on the river, be sure to thank him for developing this great pattern.
