The Mizuno MP-63 irons are big improvement

The Mizuno Mp-63 irons are big improvement on the rather bland MP-62 irons they replace. This time there is a real technological improvement with the Diamond Muscle design which increases the size of the sweet area about 1cm in each direction in a head that is the same size as its predecessor. The set also features what Mizuno call a ‘reverse flow’ where the longer irons have larger heads for a little more forgiveness. This is not particularly noticeable at address but when you hit the 3 and 4 irons it feel like you are hitting a 5 or a 6 so the principle works in practice. The grooves on the face conform to the 2010 condition of competition regulations. A visible 360 degree grind on the sole of the MP-63 offers excellent turf interaction to provide extreme workability and versatility from a variety of lies. To ensure each club can perform to its maximum Mizuno have introduced a reverse flow with larger longer irons and very compact short irons to provide a set that is perfectly balanced in terms of forgiveness and precision.
