I've always done well on jerk baits. A second rod with a Rapala Shad Rap would be my back up as the tight wobble they have really works well in cold water.
One thing that I've wanted to try but didn't get around to this year is to modify a couple of shad raps so that they would suspend in the water column. I've linked a video below of Ike showing how to modify them. I think it'd be something worth trying.
