OVERVIEW: The Ping Karsten Hybrid long-iron replacement features a larger head with a low and deep center of gravity for improved forgiveness, distance, and trajectories. It also features 17-4 steel construction and the extreme internal heel and toe weighting produces a higher MOI resulting in increased ball speed and improved forgiveness on off-center shots. The Custom Tuning Port (CTP) integrates with the wide sole to increase ball speeds and helps to produce a solid feel and sound.
