OK, I have played around summer trolling crank baits for crappie in the past, but I've never really gotten serious about it. I would like to try it more seriously and would appreciate some tips and feedback.

I surmise I will mostly want to troll in the 12 to 20 foot range (on Chickamauga Lake). In order to keep from rigging or re-rigging a whole new set of rods, my preference would be to troll with 10 lb. test mono (and leader, if needed). Prefer to long-line and not use planer boards (because I don't have any for crank baits).

I need feedback on whether that set-up will work first?

Secondly, suggestions on preferred crank baits for those depths, trolling speed, etc. Thanks for any help from anyone!
