I developed the Heltor skeltor to maximize all the attractor elements possible in one fly.
The Icelandic sheep and big fly fiber are extremely mobile in water, but their effect is enhanced by the weight of the brass beads that roll back and forth in the body tube giving not only a sporadic jerky swimming action but also rattle against each other sending out an audial signal to predators. Not forgetting the eyes which are an attack point, are oversized for additional predator impact. If you keep all these factors in mind when designing predatory patterns you wont go wrong.
