Then again, the problem may be not with the fly but with your casting. When double-hauling - especially when trying for distance - anglers tend to use extra force with the rod hand, shocking the fly line and upsetting the leader. This frequently tangles the fly. When trying for distance, anglers should use a normal, smooth rod-hand stroke with increased acceleration of the hauling hand. This results in more distance and a smooth flight of the line and leader.
