Waiting for sale of the Mizuno MP-69 irons for about one week, I can not hold on. Therefore I started to pick several for myself.

The Mizuno MP-69 Iron Set, the next iconic Mizuno muscle-back iron, was created by blending Mizuno's PGA Tour Staff input with the latest state-of-the-art design and simulation tools. This iron is the perfect balance of Grain Flow Forged feel and unmatched workability. The Mizuno MP 69 Irons feature the newly developed 4D muscle design. A strategic weighting strategy from 3-Iron through PW ensures ideal COG (Center Of Gravity) placement in every iron throughout the set to deliver total ball control and a predictable trajectory.

The MP 69 Irons are designed with precision craftsmanship to maintain the standards MP players have come to expect. Mizuno incorporates a newly developed 4D Muscle design to further optimize the Discount Golf Clubs,resulting in a consistent sweet spot height throughout the line that creates predictable penetrating trajectory. This 4D Technology combined with Grain Flow Forging gives players shot and ball control, and ultimate feel. Utilizing Harmonic Impact Technology (H.I.T.), Mizuno scientifically tunes the sound of each club head to further enhance the feel.

"Utilizing 4D Muscle design technology, the Mizuno MP 69 are a breakthrough in muscleback iron design," said Dick Lyons, VP and General Manager, Mizuno USA, Inc. "Mizuno is well known for its MP line of irons and serious golfers around the world look to us for the latest and greatest. We are extremely excited about the MP-69's and believe they will deliver game-changing results."
