The Columbia 300 Rock OnM ball is one hook monster designed for heavy oil. It features the TEC2 (patent pending) shell. The secret lies in the new core shape and heavily loaded TEC2 particle shell. The core concentrates the weight near the center of the ball for maximum roll. The large, dense flip block adds to the flare potential for more hook. This ball has a .052 differential Rg for 5-6 inches of flare. The high TEC2 particle loading puts more teeth in the shell to bite through the heavy oil. This ball will grab the lane through the oil for a midlane hook and create a strong curving backend. If you are looking for hook in oil or carrydown, your search is over. Rock On is your answer.
