Articulated flies are great, but just having a hinge-point doesnt 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.
