This stately fly was created out of frustration with the old standard Humpie patterns. I always loved the fat bodies, hair backs, and its awesome floating qualities, and I have caught hundreds of fish with them, but they have a real problem with hook-down wing-up delivery. So DFI threw a monster wedding party between Humpies and Stimulators and their first born will catch more fish than a gill net and it floats perfectly. This fly has become one of the best attractor flies I have ever fished at any elevation. You should own this fly in every color offered.
