Using a Wacky Ring on your soft plastic worm allows you to fish the same lure all day without the bait tearing after each bite or after casting under a dock or into thick cover. Wacky Rings light weight (virtually weightless) allows your lure to fall slowly and naturally, the way it was designed to fall. Since most bites come during the time that the lure is falling after being twitched/lifted, this is critical. Wacky Rings in the 3/Finesse size have an inside diameter of 3/16 when not stretched. This size is best suited for 3 inch senko / soft stick-bait style worms such as the Yamamoto Senko and Yum Dinger, or thinner finesse style worms such as those made by Yamamoto, Strike King, Zoom, Z-Man, and more.
