As a professional golf fan, I am always curious about every new products of every top brand. Recently, I have heard that Mizuno is planning on launching two new iron sets this fall the MP69 and MP59, which is the most exciting news I have ever heard before, because I pay more attention on Mizuno MP series all the time.
The mp-59 irons feature a titanium insert forged into the center of the muscle, which provides cavity like forgiveness in a player's half cavity design. And during the elaborate Grain Flow Forging process, 12 grams of pure Titanium material is forged into the muscle of the MP-59 to deliver a 5% larger Sweet Area compared to the MP-58, the iron which debuted Ti Muscle Technology, while taking home "Editor's Choice" in Golf Digest's 2010 Hot List. This provides the ideal amount of thickness behind the impact area for solid feel, while the higher density steel on the toe, heel, and sole provides a dramatic increase in perimeter weighting for enhanced playability. This design allows for an easier launch and more forgiveness due to both a lower Center of Gravity (COG) and larger sweet spot area. This revolutionary Ti Muscle technology maximizes feel and forgiveness, all in a compact players' head size.
Also, according to some testers, The mp-59 irons are amazing. They made the 59's harmonics better than then the 58's, or the 62's. The 59's top line and sole are almost identical to the 68. The 59 is a lot easier to hit. They feel so much better than the 58. I think your expectations suck then, because you obviously don't know what you're talking about. There is a lot of weight on the bottom and out on the perimeter. That is what makes the iron so great. If you want a hard club to hit then get, then get the 69.
As for the head shape of the new mp-59 irons, it has a traditional MP sized one in order to enhance workability for the accomplished player. With a Tour confirmed sole, and overall compact head shape, the MP-59 irons allow varied shot-making delivery and control for consistent ball striking from the widest variety of lies.
