You might consider trolling minnow baits off a 3-way swivel. One eye of the swivel attaches to your mainline, the next to a light line dropper to which you attach a weight , and the third eye attaches to your leader connected to your lure. You can vary the length of your dropper to adjust how close to bottom you want to be and you can add a steel leader to your other leader if you are worried about pike biting through your leader. Trolling a swim bait is another option.
