Colors can be critical, so it pays to have some variety in your arsenal. We do well with chartreuse, lime green, white, pink or shad patterned plastics like Panfish Assassins, Bass Pro Stubby Butts, or any variety of tubes and twisters that run from 1.5 to 2.5 inches long. There are days when one particular color seems to get all the attention, so it pays to experiment. To hook more soft biting slabs, open up the gap of the hook on your jig so that it is wider than the standard 'j' shape as it was purchased from the store. Cold weather crappies often hit lightly and don't hold on very long and the open gap enables better hooksets. Sometimes, you'll need to cast farther or go deeper with the small jigs. That's when we pinch on removable split-shot to adapt to the situation.
