Mizuno JPX-800 and JPX-800 Pro irons

Mizuno is synonymous with forged irons. Discriminating golfers around the world – whether they play Mizuno or not – invariably express admiration for the design and appearance of Mizuno irons.

Mizuno is introducing three new forged irons plus a new cast iron for next year. All have the reduced grooves.

The new forgings are the MP-63, MP-53 and JPX-800 Pro. The cast iron is the JPX-800.

In the past, Mizuno has used different names in the West and Far East for its game-improvement products. In Japan, the name was JPX, while it was MX in the United States.

Now, all the game-improvement clubs worldwide will be included under the JPX umbrella.

Some skilled players will be interested in the JPX-800 Pro. This iron combines the best features of two previous Mizuno irons – the MX-200 and MX-300 – and adds the highest COR (ball speed) of any Mizuno forged iron ever produced.

The look of the JPX-800 Pro is similar to that of the MX-300, while the forgiveness is straight from the MX-200. The JPX-800 Pro, like most Mizuno irons, requires a taper-tip shaft, preferred by touring pros. One of the taper-tip choices is the new Project X graphite iron shaft from True Temper. Project X graphite (approximately 93 grams raw weight) is built to mirror the performance of Project X steel (about 115 grams).

While the JPX-800 Pro is a one-piece forging, the JPX is a complex cast design featuring a pocket cavity and a thin high-COR face that produces what the company is calling “the longest Mizuno iron in history.”

The MP-63 and MP-53 replace the MP-62 and MP-52, respectively. The 62 and 52 will remain available from the Mizuno custom department at their current retail prices.

The MP-63 is the iron that will be used by most members of Mizuno’s touring pro staff. With subtle changes in weight distribution, the MP-53 is somewhat more forgiving, although the two iron models have identical retail prices and can be mixed and matched.

Both feature what Mizuno calls a 360 Grind, meaning there is a grind or bevel all around the head. Looking at the sole, this grind is aimed at eliminating any turf drag at the toe and heel.

The 360 Grind was originated for the Mizuno MP T-10 wedges and has been carried over to the MP-63 and MP-53 irons. Both have a slightly beefier sole and top line than the 62 and 52, although this has been disguised by the beveling.

To facilitate different lengths and other custom specifications, all four new iron models are available in two separate head weights – standard A weight and lighter B weight.

Mizuno also is introducing new MP T-11 wedges for 2011. These wedges have the new grooves and vary in loft from 50 to 64 degrees.

Mizuno MP-63 and MP-53 irons

The skinny: Mizuno’s new top-of-the-line forged irons, these two irons are similar, although the MP-53 is designed to be slightly more forgiving on off-center hits. Both irons contain a diamond shape in back, intended to provide mass and proper acoustics. The irons are the product of Harmonic Impact Technology, in which Mizuno synchronized sound and feel; the company even consulted university professors specializing in the study of musical vibration. 

Cost: $899 (eight irons with Dynamic Gold steel shafts)
