The key to all structure FOR FISHING (not including spawning or protection purposes) is location , location , location.

One piece ( like a PPFA) alone in the wrong place will help but is not the right use. Look at Nate's vid and notice the other items with it like plants and elevation changes. Using structure across points , along ditches and near feeding locations , in funnels , on humps - think ambush places for predator fish.
