When we first stocked the J Heads around 5 years ago, to be honest we didn't know exactly what to do with them. We didn't really supply a range of freshwater kit, and these heads just weren't useful to us in SW.
The weedless wire design is very versatile. We suggest bending the two wires apart (as pictured). The point is you can twist and angle them to suit your own preferences. They match perfectly with the likes of the 2" and 3" Fish Arrow Flash J lures, but work great as part of a Ned rig setup. Check them out on the Flash J Bug 2" as well!
Tungsten weight keeps the size very small and compact, and gives much better bottom contact/feeling.
