Snake Eyes VNM Iron Head: Mid-size design on the Snake Eyes VNM Iron Head provides maximum forgiveness. Deep, undercut cavity provides solid feel at impact, while the unique progressive sole design promotes accuracy. Within the undercut back cavity a special urethane insert gives a powerful, solid feel at impact. The CAD-designed, vibration-dampening system incorporates a two-part energy-absorbing insert that decreases negative vibrations resulting from off-center hits. These innovative iron heads also feature a reverse progressive sole design with the long irons having the widest sole widths progressing to medium-wide sole widths in the middle and short irons. This places weight low where it is needed most in the longer clubs, resulting in high-flying, soft-landing approach shots.
