Shute, who personally ties every lure, explains that his original model was a 3-ouncer, but he added lighter and heavier versions, and did a little innovating. The Keel Weighted models keep the bait and the split color of the lures running dark side up, light side down. He designed the Flat Liner, an 8-ounce model, specifically for bigeye -tuna, which rise on a flat-line bait so hard, the bow wave they -create throws lighter lures out of the way. The Big Hole -series was initially designed to be used over hookless baits on dredges, but they quickly found other uses. Anglers who buy pre-rigged ballyhoo could just slip the loop eye through the oversize hole and drop it into the spread, and they made quick-changing lures a breeze. No having to rerig the ballyhoo, just unclip the rig, slip one off, and slip on another. The Yellowfin model in 1 and 2 ounces is ideal for canyon fishing with small and medium ballyhoo, and West Coast striped marlin sharpies have been using it to do the job on their local marlin population.
