I have found pulling cranks a great way to cover a lot of water in a short amount of time and being very effective while doing it.
In the beginning I would try to choose color based on the bait found within the lake you fish. For size I believe it was once said, “Big lures catch Big fish.” I would start by running the crank just off the bottom. I have found it more important to find the right color, size, and running depth as opposed to the name on the side of it.
Pick a bait color, nice sized crank and run it on the bottom. You can fine tune and get as technical as you want after that.
