Articulated flies are great, but just having a hinge-point doesn&';t mean they will waggle better than a conventional streamer. You need some bulk up front to deflect the water and make the back half kick. The Mover and Shaker has just the right mix of a water-pushing head and a super mobile zonker rear section to ensure that the fly darts side to side on the strip with plenty of pulsing movement . Huge trout - measured in feet not inches -fall prey to the Mover and Shaker.
