Introduced in 2009. By maximizing perimeter weighting, these irons boast an MOI that’s 10 percent higher than their predecessors. The ideal CG position has been preserved, generating optimal ball-flight trajectories. The Modified Tru-Bore design has been incorporated, dampening vibration for enhanced feel and the tour-inspired head shape has a slightly thinner topline and sole with a large sweet spot for improved aesthetics and forgiveness that will boost any golfer’s confidence.
