Yes, using an O-ring for a wacky rig is beneficial.
An O-ring helps secure the soft plastic lure in place on the hook during fishing. This prevents the lure from sliding down the hook while casting or retrieving.
By using an O-ring, the wacky rig becomes more effective and has increased durability. It allows the lure to move more naturally in the water, enticing fish to bite.
Without an O-ring, the soft plastic bait can tear easily, reducing its lifespan and costing you more money in the long run.
Overall, adding an O-ring to your wacky rig setup can improve your chances of catching fish and extend the lifespan of your soft plastic lures.
