Hull's 1/2 Way Gray Drake Comparadun is a true guide fly and a CFA original. Developed to be a more durable version of the original comparadun as well as the sparkle dun. This fly floats well because of the synthetic materials, while maintaining it's comparadun wing profile. The tail simulates an emerging nymph right before it shakes it's shuck, so about, halfway to emergence or so. This particular version of the 1/2 Way serves well as an Adams & Parachute Adams replica so try the smaller sizes as well.
