Monkey Lures Fat Lui (Sour Snapper/Flash Series) The Fat Lui has been specially developed for pike fishing. The voluminous body in combination with the protruding blade tail creates a strong flanking and extremely realistic swimming movement that extends over the entire lure including the head area. Even with the slowest pull, the Fat Lui runs seductively due to its soft rubber compound. The extra large X-eye serves as an additional stimulus and directs bites to the head area of the lure. The Fat Lui is mounted in the classic way on a lead head, a screw head or a Shallow-Srew.
