"We built the SPRO Little John crank baits to run at depths of 3 to 5 feet. We used a computer chip board for the lip to create more feel and to be more durable. A silent weight transfer system using soft tungsten translates into incredibly long casts for a small crank bait, even in windy conditions. We used the world's sharpest trebles - Gamakatsus. I think the SPRO "Little John" crank baits are the best shallow running crank bait available. Period.".
