For trolling suspending fish over deep structure in winter, a deep-diving crankbait is the strongest match from the retrieved set. The Heddon Magnum Hellbender is built to get very deep and work along steep banks and structure, which is useful when fish are holding tight to bottom or suspended near breaklines in cold water.
Switch to a different presentation if fish are clearly suspended well off bottom, won’t commit to a crankbait, or are holding in very cold, inactive water. In those cases, a slower bait or a more vertical presentation is often better than a diving plug.
