Had no results with cranks myself. Then, quite by accident, I got strikes when the crank would smack into things likes rocks, logs and generally the bottom.

Came to realize (late) that this is expected and common.

not going to lie, Rapala X-rap. One hell of a jerk/slash bait! was killing them up north in NY in the summer. Lakes up there are crystal clear though. I have fished it down on Smith Mountain Lake in cloudy water. Had a few fish on the ghost white color. I think that the X-rap is worth a shot if you are looking at picking up some jerkbaits.
