I recently purchased the Mizuno MP57 Irons and could not be happier. My previous set of irons were the Callaway Fusion with R flex graphite. The Fusions are great irons. I originally bought the Fusions for distance and soft feel, but I have learned that I sacrificed accuracy. Though I could hit them a long way, I could never seem to hit them with consistency. Shot dispersion was unpredictable. I attribute that partly to my swing and partly to the graphite shaft. Also with the Fusion I had difficulty diserning well struck shots from poor ones. They all felt the same. After hitting a friend's Mizuno MP irons at a range, I was really impressed with the consistency and accuracy. I demoed some clubs and decided to purchase the Mizuno MP 57s with R Flex Dynamic Gold. I quickly realized that the Dynamic Gold shafts were too stiff and harsh for me. I spoke with a Mizuno rep and he recommended the Dynalite Gold SL shaft, which I demoed, but the ball flight was too high. After doing some research, I elected to reshaft the MP57's with True Temper Black Gold shaft (which I soft stepped by 2 shafts) and WOW what a difference. I am ecstatic with my MP 57's. They are EXTREMELY accurate, and the Black Gold shafts provide a medium trajectory piercing ball flight with absolutely no harshness. In fact I have never played a steel shaft that felt so smooth, with virtually no sense of vibration. A well struck shot feels effortless. I admit, I can't hit my MP 57s as far as the Fusion, I'm about 5-10 yards shorter, but I am alot more accurate and consistent, and I can disern if my shots are solid or thinned or toed, etc. You hear that the Mizunos (especially the MP series) are "Players Only" clubs, but I am an average golfer, and can play the MP57 (with Black Gold shafts) with no problem whatsoever. In fact, with the improved accuracy, think they will improve my game substantially. I am already hitting more greens in regulation, and can actually hit the 4 iron which I could never do before. Just a final note, Mizuno does not offer the Black Gold shaft, you have to reshaft it yourself or get a Custom Clubmaker to do it for you. I reshafted the set myself and soft stepped them by two shafts to lsoften the flex from R to A(A+). I am an equipment junkie, and an amateur clubmaker and I am always looking for clubs that fit my swing and my game. The MP 57s are the irons for me and I will stick with them for a long, LONG, LONG time.
