If the selected fishing area has submerged brush tops, the proper depth will usually involve the lure just brushing the limbs. Obviously, the slow retrieve will preclude hang-ups. Lipped crank plugs run slightly nose-down and will actually crawl over most of the potential snags. If the lure does hang momentarily, give it a bit of slack and most will float free. Be prepared for a hard strike at this time.
Standard tackle is quite satisfactory for presenting shallow crank plugs.
It is recommended, however, that the angler steer away from fast tip, 'whippy' rods and those shorter than five and one-half feet. The stiffer, longer rods will give a bit more 'feel' of a soft strike and assist in the rapid hook-set so often required. For weight, comfort and responsiveness, graphite is the better rod choice. Line weights are a matter of preference of the angler, given that he considers all the factors present. Lipped crank plugs have a good bit of bass-attracting action and vibration inherent in their design.
