"I use EP™ PLASTIC EYES in all my streamer fly patterns, and the reason is very simple - the trigger point of a predator fish is in the eyes and the gills. EP™ PLASTIC EYES are not only three-dimensional and realistic, but they also add a little weight to the fly. My preference for attaching these eyes is with Goop, check out the video in my Tips and Tricks section where I show you how easy it is to add these eyes to your fly."
