Shimano Butterfly Flat-Fall Jigs are a totally new concept of Butterfly Jigging technique. Drop the jig down to the bottom, then crank it up 30 feet off the bottom and free spool. Or cast the jig and let it fall while free spooling, wait for the bite, then jerk and repeat. The center balanced jig falls with a wobbling action in a horizontal position, keeping the jig in the strike zone longer.Features:a Hydrodynamic flat keel designa Center balanced jig flatten on the falla Two Owner dancing stinger hooks with PowerPro 300lb. assist 42g = 1.48oz 60g = 2.11oz 80g = 2.82oz 100g = 3.52oz 130g = 4.58oz 160g = 6.64oz 200g = 7.05oz 250g = 8.81oz
