Fly Silhouette

You have a trout come up and inspect your March Brown Dry fly but refuse it. You show him a Light Cahill but no sale. You show him a Quill Gordon but he will not take it. What’s wrong? Could be these patterns were too similar in the silhouette the trout saw. The next time trick him!! Go from a March Brown to a Letort Hopper to a Murray’s Flying Beetle to a Mr. Rapidan Ant. These are all different enough in silhouette that he’ll probably take one.
