When casting crankbaits for walleyes one of the best triggering options is to occasionally stop the retrieve. By switching the rear hook on a crankbait to a feathered treble you can double the effectiveness of your pause. When the bait glides to rest the feathered treble adds a subtle enticing action to your crankbait. Feathered trebles also add more color to your cranks and can serve as a spot to apply scent to your lure.
