CRANKBAIT TIPS:
*  Small, buoyant crank baits can be worked through lily pad fieldsby guiding the lure's movement with the reel tip.
*  Try jigging rattling, lipless crankbaits up an down next to vertical structure like timber or bridge pilings.
*  Paint a red gill or gash on the bait to signify blood or gills.
*  Work shallow driving crankbaits in deep water by rigging them Carolina style with a heavy sinker, barrel swivel and monofilament leader.
*Make crankbaits swim to the side and under surface cover by bending the line-tie eye slightly to one side.
