Zacatak's Large 12.5" Sprocket has a tight swimming action that is effective in all conditions, at any trolling speed. If we could offer only one piece of advice it would be to run a Large Sprocket in Green Luminescent on the long rigger... and leave it there! Even if it takes a while, once it starts nothing else will come close. Fish find this lure irresistible! We also recommend the Blue Green and Dorado skirt combinations.
