The Little John 50 was designed by Professional B.A.S.S Elite Series Angler John Crews. When John Crews designed the Spro Little John, he wanted a bait that would allow him cover shallow 3-5ft water quickly and effectively. Crews also wanted a durable yet sensitive bait that could be cast long distances with great accuracy. The Little John 50 has a computer chip bill that is more durable than plastic, a silent weight transfer system using soft tungsten translates into incredibly long casts for a small crankbait. We used the world's sharpest trebles made by Gamakatsu. The Little John crankbaits are the best shallow-running crankbait available and comes in an array of fish-catching colors.
