Mizuno JPX 900 Driver


The most adjustable driver ever?

Mizuno JPX 900 Driver
The Lowdown
– Mizuno's most adjustable driver ever
– Designed to be easier to hit and longer on miss hits
– Designed to feel solid in every weight setting
The Detail
Want a set of awesome irons? Most golfers will look first at Mizuno, Titleist, Callaway, Ping, TaylorMade, and Cobra. Want a new Driver? TaylorMade, Callaway, Ping, Titleist, Cobra spring to mind.  Maybe not in that order, but you get the idea. Mizuno aren’t normally the first choice for people looking for a new driver. They aren't second, third, fourth or fifth choice either. 
Mizuno JPX 900 DriverRightly or wrongly, people haven’t thought about Mizuno as a driver company in recent years. I’m a bit older than some of you, a bit younger than some others. But when I was a kid Nick Faldo won the Masters with a pair of T-Zoid woods. Vijay Singh won a Masters using a Mizuno 300S driver. Mizuno made some of the first carbon crowned woods, and they were there right at the beginning of adjustable drivers. But because they haven’t paid tour pros to use their drivers, they aren’t seen as the drivers to have. 

Part golf club, part Optimus Prime, we think the new Mizuno JPX 900 driver is the driver to change all that. Look at it. It’s a driver that’s travelled back in time from the future to protect us! Mizuno have stuffed so much tech into this driver, we half expect it to hit our tee shots for us. In all seriousness, a driver needs a certain ‘X Factor’, some shelf appeal that helps it stand out from the crowd. The JPX 900 has it in spades, screaming ‘just hit me as hard was you can.’Mizuno JPX 900 Driver
Mizuno set out to make a more forgiving driver because their Tour players asked for it. If you look at what is being played out on tour at the moment, many players are using more forgiving drivers. Every man and his dog seems to be using a TaylorMade M2, while two majors were won using Callaway’s XR16, the most forgiving driver in their range. Like the rest of us, tour players miss the sweet spot too, and the big thing for them is that the driver goes as far as possible on miss hits.

Not only did they want it to be easier to hit, the pros asked for a driver that looks easier to hit as well. So they stretched out the head design, it’s longer from heel to toe, and wider front to back with a shallower face. 
The face has been redesigned and strengthened to help with miss hits. You can miss the sweet spot and your drives will retain more ball speed and go closer to where a perfectly struck drive might land.

There are three weight tracks on the sole, and two 8 gram weights. You can put the weights in the back for maximum spin and forgiveness, in the front for the lowest spin, or in the heel and toe to make the driver more draw or fade biased. We found it pretty good with the weights in the front heel and toe positions, it made the driver low spin but stable on miss hits. 
The hosel is adjustable for loft. You can set this driver as low as 7.5 degrees, and as high as 11.5, with it set to 9.5 in the neutral position. Changing the loft of a driver changes the face angle as well however. So Mizuno have added a face angle adjuster, so the driver can be made to appear open, closed, or square, independent of the loft on the face. This only works if you ground the club. But even people who hover their driver tend to put it on the ground as they grip the club. 
Another big thing is this driver is designed to feel great. Sounds obvious but you’ll be surprised with some drivers out there. Adjustability in driver and moving weights around the head can make them sound very different depending on how they are set up. The JPX 900 has been designed to sound and feel the same however the weights are set up. We’ve only hit it indoors, so I don’t want to comment too much on the sound, but it feels really solid.

The finishing touch is the Fujikura Speeder Evolution II Shaft series included as a stock option. The orange chrome shaft is a real eye popper, and with varying weight and flex options, there should be something to cover most if not all swing types. And this is the real deal, as used on tour shaft, that would retail for around £270 on its own!
Mizuno have got a driver that has a serious shot at making a lot of golfers bags. All the changes the tour pros asked for are also changes that will help the average golfer. It’s a driver that just begs to be hit, and can be hit by just about everyone. The driver launches in Europe in the new year but is already available in the US for any American readers out there.

Does aerodynamic drag reducing Driver designs really "add distance to your game?"

From a designer and an engineer who know more then most of us:

"When Adams was the first to bring out this BS claim about aerodynamic improvement with their Speedline model some years back, I shouted BS on this when I could.  There was the marketing for this model showing the head sitting in a wind tunnel with the smoke blowing over the surfaces to drive home the point to the consumer about how this has to really matter. 

When a golfer swings a driver, the head is rotating continually on the downswing so the face surface never is presented to the "aerodynamic drag" until the very last few thousandths of a second. The surface of the head that is normal to the airflow during 98% of the downswing is curved anyway - it is the heel surface which has less drag by far than the insignificant face drag is. 

Upon watching this commercial showing the Boeing people, I could not help but think if the Boeing engineers had a big laugh about the money Callaway undoubtedly paid Boeing in the face of what a good engineer is going to know is insignificant. And who do you think has the engineers that know more about air flow and drag to know that this is insignificant on a driver head?

Sure, drag is significant, for a bullet flying at 3,000 fps. For a clubhead at 120 mph (which is Bubba Watson type clubhead speed, not most golfers) which equates to a velocity of 176 fps, the change in drag one can effect by contouring a 460cc clubhead is so small it is meaningless".

Wedges: Conforming vs. Non-Conforming Grooves

Are the new grooves capable of producing as much spin as our old beloved square (and now non-conforming) grooves? Could the hoopla surrounding the 2010 groove rule have been much ado about nothing?
It's certainly worth looking into.
We had two golf professionals test new conforming grooves against the older square grooves, and the results suggest that, from fairway lies, grooves actually don't make a heck of a lot of difference!

Test Objective and Conditions

Here is what was tested and how we went about it:
For this test our objective was to determine what, if any significant, difference exists between the current USGA legal C-C (condition of competition) grooves and the old (non-conforming) square grooves from fairway lies.
Our test conditions were as follows:
  • We used two almost brand new 56 degree clubs with near identical specs. The difference between the two was that one had C-C grooves and the other had square grooves.
  • Two golf professionals hit 15 shots each from 3 different distances with each club. Data from the best 12 shots (24 shots per distance) was used for the calculations.
  • The measured distances were 25, 50 and 75 yards and the objective was to carry the ball to that distance.
  • All shots were hit with premium golf balls except the shots hit from deep rough.
  • All shots were hit from a tight mat so as to limit outside factors interfering with friction between the face and the ball.
  • As a point of interest each tester also captured data on five 50 yard shots from the rough with each club.
  • The Results


Observations & Analysis

There were no noticeable differences between the two types of groove and both testers reported not being able to tell the difference between the two clubs in how the ball reacted off the club face.
For the shots out the rough we hit from very poor lies in thick Bermuda and the golf ball was coming out and knuckle-balling through the air. You could clearly see the ball change direction in mid flight. I don't believe there are any grooves out there that could significantly impact the flight of the ball from these types of lies.

I do believe that when tested in a strictly controlled laboratory type environment, and with a much larger sample size square grooves might show that they spin the ball marginally more than the current C-C grooves. However, our tests indicate that the difference might be so minute that not even golf professionals are able to identify a difference.
A side note to keep in mind is that in order to hit chip and pitch shots that end up consistently close to the hole we don't need maximum spin, we just need enough spin.
Whatever grooves you're currently using, as long as they're clean and not worn down will be able to get the job done.
