The rods that produce the most fish mainly depends on how deep the water your fishing is, and how deep the fish are positioned in the water column. If trolling deeper water, for deeper fish any rod will be as good as any other. If trolling a specific contour, using your depth finder as a guide. The back rods will produce best, as the jigs being pulled will travel over the same water the depth finder went over. If fishing shallow water, or fish that are way up in the water column. The outside rods will be best, as the boat will spook the fish, causing them to scatter.
