It depends upon your depth and I was running in 8'-12' water, so I used the short-bill shallow running cranks. I was trying to run about 4'-6' deep. If you go to a little deeper water, the mid-depth cranks will work.

Here is the best source of information available in America: http://www.crappie.com/crappie/missi...-cranks-101-a/

There are 157 pages to this thread, so get ready for a lot of reading. It will tell you everything you ever wanted to know about pulling cranks. They work best on white crappie and Jordan/Harris are mostly black, but the perch sure love them.
