Pulling cranks is something I enjoy doing. It might be a little boring but it's about the only time I actually get to fish and not worry about boat control the entire time. With jigs, you're generally in a common area with people and constantly have to worry about where everyone else is. If I tear off, I have to spend the time tying on and watching where the boat is going, doubling your time out of the water. Back to cranks. I think you can make it as simple or complex as you want. Following dive charts, lead core, down rigging, etc. adds some better knowledge and work load. Find a depth, drop the cranks back til they bounce, reel up a bit and troll away. Play with the speed to see what they like. I generally keep it in the .8-1.5 mph range. I've been going as fast as 2.5 mph some times. Watch the rod tops to see if they have a nice vibration and keep an eye on the graph.
