I was on Elk Creek, Pennsylvania, about a week ago-after steelhead. Lots of spin fishermen and a few fly fishermen. This one fellow came up near me and cast out a streamer (minnow pattern)that looked to be about 2" long. It had a tail about half the overall length- possibly rabbit fur.. In any event this was a pool with little current- almost still water. He jiggled the tip of the rod and slowly reeled in line (not strip) and this streamer quivered and fluttered as it slowly moved through the pool. It was chrome and gave off a lot of flash- looked JUST like a minnow. I didn't get that good a look at the fly but it was either a chrome/Mylar tube or tinsel wrapped body.
It was pretty incredible, he would drag this in front of a holding steelhead and get a strike on about every cast. I think he caught 6-7 good sized steelhead almost one after another. A strike on about every third cast.
The best I can do is make a streamer dart in little 6" spurts but no flutter. Is there a certain kind of fly and technique that creates this fluttering?
The pool was about 2' deep and this fly had a neutral bouncy as was mid-depth as it was slowly brought in.
