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.
