I have spent many hours pulling cranks on the Hill. White crappie will hit cranks faster than blacks but both can be caught. I like to use cranks once the water warms into the 80's and work the deeper waters from midway of a creek run back to the main river. Most times you will find a sweet spot/depth and be able to have a good catch. If you have a weak heart you may not want to pull cranks because you will lose some, I have had days when loosing 5 would happen.
I pull six rods with 10 lb braid and use line counters. You need to know how much line you have out. Myself on most days I pull two 300 on the two center rods, 200 on the next two rods and 100 on the two outside rods. All cranks pulled with the same amount of line out. You will cover the water column pulling like this plus you can pull closer to the bank without hang ups if you decide to fish the banks.
As for charts go to the Bandit home web site and search depth chart, they have one for all their cranks or at least they had them. If you don't see them let me know and I'll post a pic of my chart. For the speed 2 mph is the speed I use all the time. A good trolling motor set at 5/6 and a strong set of batteries will get you through half a day or over pull at this speed. Colors, dark in the early morning and lighter colors as the sun get high in the sky.
Don't over think pulling cranks, put them in the water and enjoy the time on the water. Pulling cranks isn't for everyone as you will like it or not so start out with a small amount of cranks and if you enjoy pulling you can add to your arsenal. There are many other cranks that will work besides Bandits so keep a eye out for sales on cranks.
Hope this will help you in deciding if you want to pull and gives you some helpful info.
