I troll 'em on leadcore for walleyes. Unfortunately, they also catch tons of bass. Less unfortunately, they also catch just about every other species that swims. And the factory trebles are Mustad Triple Grips, designed to hook 'n' hold when trolling with no-stretch lines. Good quality bait, easy to tune, has a wider wobble than fat-bodied bass cranks. Worth keeping a few around, both for trolling and casting.
