It's great to keep a log of what worked last year but never ever live by it..... my favorite saying is listen to the fish, they will tell you want they want, where they want it & how they want it..... always always give every option a try weather it be depth, jig color/size, action & type of structure. Skip brought up something I have found crappie are usually always happy near drop offs & those drop offs allow one to try several different depths to find where they will feed....FEESH ON....
