Here’s a presentation I enjoyed on The Fly Culture Podcast with Pete Tyjas about surface and subsurface trout feeding behavior that is based on observation using technology (video/film) and therefore factual. For Dries it is flies that portray vulnerability (spent flies/spinners; emergers; stillborn/ cripple; stuck-in-the-shuck flies, drowned looking flies; etc.) to a trout that get selected more often, sometimes solely. These are dry flies that sit/ride low, “in the film”. Good flat-water anglers have long known this. Hayes and Stazicker confirm and add to the knowledge base.

Make your ties look vulnerable…fish the ones that are soggy and look beaten-up!
