These powerful max game-improvement irons pick up where last year's C200 irons left off. "The refined and improved ‘FLX Face' technology is the highlight of the D300 and players will love the distance increases they see, but there's also maximum MOI and great feel for an oversized, forgiving head.
Updating the ‘FLX Face' technology (the wall thicknesses have changed as well as spacing and length for the "power holes") bolstered its effectiveness in the larger, more forgiving head. Again, the "power holes" around the entire head create space for the face to flex more at impact and generate faster ball speed. The holes also free up mass that's repositioned low and back (there are weight pods in the heel and toe) to increase perimeter weighting for added head stability. The holes get filled with a urethane material, which controls vibration and is malleable so the face can flex easily.
