The Mustad Heavy Duty J-Assist 2 Rig is designed for deep sea jigging. Featuring a heavy-duty Kevlar loop tied to the wide gap Mustad hook with high quality materials. The cord is usually looped onto the connecting end of the jig so that the hook is positioned behind the head and belly area of the jig to improve hookset, as the fish often strikes at the top end. Another benefit is less snags because of the absence of the traditional tail treble. The assist hook is dressed in green tinsel to attract attention, creating a striking point. These hooks were tested over a period of 2 years by Mustad's pro staff before they were launched.
