The Stringking Mark 2V head is the second generation offensive release from the pioneers in next level pocket technology from the West Coast. Stringking engineered the Mark 2V with 29 strategically placed stringing holes that allow advanced stringers to really dial these heads up for the optimal combination of feel and release for specific players.We really like the aggressively angled scoop as well. This makes the ground balls funnel quicker and deeper into the mid pocket. Stringking also added an optional bolt system with these heads. While a little tricky to install, it will totally eliminate ball rattle.
