Pushing cranks tends to not work in the northern locations. Just like spider rigging. Our water is much too clear and many of the fish are simply boat shy. For this reason, many pull out the back of the boat and incorporate planer boards into the spread to get the offerings away from the boat. I would love to be able to push cranks as it would be much easier to manage multiple rods without having to clip on planer boards. Much more effective technique for sure. It just isn't possible with our water clarity in most lakes.
