The original Flash Mob Jr. had spinnerbait clevis holding the blades on and they used really thin wire snaps and swivels. Those first couple of years, I broke off blades and lost some bigger fish especially big stripers with the components those early models had. Now the the blade spins freely inside of a modified knuckle (see slide 4) and the swivels and clasps are beefed up to offer a lot more strength and durability. I will fish the same rig sometimes all year.
Usually when you snag or have issues, you bend out the hook on the jighead or dull the hook and just swap out the jigheads. I have had a wire break occasionally but that’s usually because you bend the wires in and out and they finally weaken. Just be mindful of that and it will last a long time.
