On recent trips to La Zona, low water gives the opportunity for one to use topwater lures to catch monster golden dorado. I found the ISCA Marine Sports TNT 140 to out produce the other large prop lures made for peacock bass by a wide margin.
However the TNT 140 is practically impossible to buy in the United States. Kermett Adams of http://www.klures.com/ can create a similar prop lure. I tried out Kermett's prop lure on my last trip to La Zona and found it to work well. It creates a large "woosh" sound when jerked and puts out a big wake from its prop to call in the monster dorado.
Contact Kermett at http://www.klures.com/ for more information on these and other great prop lures Kermett makes for golden dorado and peacock bass.
