Big predators like big flies!  Specifically designed to lure the largest Temensis Peacock Bass from the midst of a lagoon when fished with a sinking line.  Being relatively buoyant these flies also work well when fished close to structure, floating until your line has had a chance to sink and then on retrieve will pop under the water and fish at the line depth on the retrieve, avoiding unnecessary snags.  Fish with a fast sinking line for best effect.  Tied on a Gamakatsu  SL-12S Hook.  7 ½  inches long.
