It's for: All skill levels
G20 irons showcase the same head profiles, sole thicknesses, lofts and shaft lengths as G15, along with several new features that aid feel, forgiveness and distance. Ping engineers, for example, strengthened the "Custom Tuning Port" (CTP) in the rear cavity. The reinforced CTP combines with an elastomer badge to reduce face vibration and dampen shock. The thinner, lighter face allows four grams to be shifted more rearward in the head. The payoff should be more playable misses, a higher ball flight and slightly more carry with the long irons.
