JRI Custom Lures JRI-1 Surface Iron Jigs are the smallest Surface Iron in the JRI line up. A great jig when fish are keyed in on small bait or are really active chasing bait on the surface. The swim pattern is erratic with a fast kick out. A medium to medium fast retrieve works well with the JRI-1. Yellowtail, Barracudas, Bonito, and just about anything feeding on the surface will fall victim to this jig.
