Who are the 4D Muscle design Irons? The answer is Mizuno MP-69 Irons, the best golf clubs on sale from 2011 to 2012. At the same time, Mizuno also introduce their best golf MP-59, the next generation of our award winning Ti Muscle Technology, delivers full cavity forgiveness in a player's half cavity design. And the new MP-69, the next iconic Mizuno Muscle Back iron, was created by blending our PGA Tour Staff input with the latest state of the art design and simulation tools.
The new 4D muscle pad on the back of the MP-69's clubhead, strategically places the weight progressively through the set to produce easier-to-hit long irons with a slightly higher ball flight than before, whilst the shorter irons remain cleaner and more compact with a high center of gravity for improved trajectory control. The MP-69s offer great levels of feedback thanks to Mizuno's Grain Flow Forged clubheads, which produce an improved impact sound and feel. Lastly, the Mizuno MP-69 Irons feature an evolved sole design with a more beveled trailing edge for cleaner turf interaction.
In these days, the Mizuno MP-69 Irons have stepped into our world. I can not control myself to have a test with them. To be honest, I think they are a little expensive; as a result, I just have a try. I will add them into my bag until they cost less.
