A blank leadhead has no hair, feathers, or further dressing on it, simply the lead molded onto the hook. A gob nightcrawler is placed on the hook. This new technique incorporates the hook, weight, and bait into one unit. The best feature of this rig is that it is much more difficult for the bullhead to swallow the hook. The drawback with this method is obvious since the weight is tied directly to the line.
Bullheads are predominantly bottom feeders, making the use of a bobber or float unnecessary.
It may actually keep the bait away from the bullhead by keeping it off the bottom or by moving the bait away from fish on a windy day. Even the most inexperienced angler can discern a bite without a bobber as bullheads rarely bite so lightly that they don't move the line or rod tip. Leaders, either steel or nylon, are not necessary to fill a stringer with bullheads. In the days of black-braided line, leaders were used to keep the bullhead from seeing the line. With the invention and improvement of monofilament line, the hook can be tied directly to the line, and the fish is none the wiser.
