You can target both bluefish and blackfin bass with one minnow! rock drift. The Rock Drift, which has a small body but has a strong rolling action and enhanced range-keeping ability, was developed with the assumption of targeting blue fish by adding a strong jerk to high-speed retrieve. In addition, in selective blackfin games, we have developed it to appeal by swimming well from outside the cage, and within the cage, to let it float naturally with a buoyancy setting close to suspend.
