Spun deer hair or cork or foam head poppers on a sinking flyline.
The fly is pulled down on the strip and will slowly rise on the pause. The fly should only pull the leader up with it not the flyline. The sinking flyline should only allow the fly to rise up to the length of the leader. The system works best with bluegill poppers and such size flies.
Use which ever sinking flyline needed to get to the depth you want to fish.
