Smile Blade® SpinDrift® Walleye

Does the swivel on the SpinDrift hook scare fish away?

No, the swivel-to-hook system creates a rolling action on the bait and is typically covered by the bait.

Does the single hook work as well as a two-hook set up like a crawler harness?

Yes, with the slow roll created by the technical bend in the SpinDrift hook, it triggers the fish to want to attack or bite a little differently. You're also likely using a smaller piece of crawler, so it is a more compact lure.
