Comparadun

The Comparadun is one of the most universally effective fly designs for matching mayfly hatches. Because there is no hackle, the body of this fly rides flush against the water; it presents a well-defined profile of both body and wing and makes an excellent flat-water pattern. Yet the deer-hair wing gives this fly good buoyancy, and it can hold its own in the rougher stuff. If rising trout refuse this fly, you can trim the wing to a stub and fish the pattern in the surface film-it makes a highly credible emerger.
