Just a suggestion to those wanting to start out using crankbaits.
1. Start out with arkies or bandits or both
2. Crankbaits only, you can't go slow enough for longining jigs, just concentrate on the crankbaits.
3. Print out the depth charts for the Arkies and bandits and tape them to your tackle box so you can study them while cranking.
4. Do yourself a favor and learn from the guys that developed this technic of fishing through their constant experimentation,,, read http://www.crappie.com/crappie/missi...-cranks-101-a/
it will teach you everything and all about using trolling motors, boat speed, depths, you name it. Sure it's a long read, but it will answer all your questions as well as give you ideas how to set your boats up.

just my 2 cents
