Re: Mizuno ST180 Driver

Some inaccurate stuff in the MyGolfSpy piece.  ST180 doesn't replace the EZ.......only in the sense that the EZ is no longer available and the ST180 is.  The EZ irons aren't available either - but not replaced by the MP-18 MMC (same situation).

We spent some time with David Dixon yesterday - an easy start point as he's been playing the JPX900 (no one hounding him on the range every week to switch drivers).

He got all the numerical gains - yards (i won't say how many), mainly from a drop of 300 rpm and 1 degree higher launch. But he really wasn't interested in that - didn't even ask to see the numbers.  He would have dropped 5 yards to take out a miss left from his game - which he did at the 9.5 degree setting.  His JPX900 was set up at 8.5.....and he still has the odd miss left in it.

His favourite Mizuno driver to date was the MP-650 (common theme) - because of it's 'ant-left' trait.  Had nothing to do with looking pretty etc.  Purely the flight.

From yesterdays testing the ST180 looks to have that same anti-left built in (at the lower lofts)....with the low spin / high launch most of the tour guys are after.

Some pics alongside the JPX900 below - just to show this is nothing like an EZ.

Anti left? That's been the bain of my life for ages. Might try messing with the loft again on my 900 :)

How does the head size compare to the 900? Is it staying the same at 450cc.

It's around the 460cc mark again.  Seems to depend who measures as whether its 450 or 460cc.  As long as USGA /R&A approve, we're happy.

I don't know what it is about the pictures of this new driver that makes it appeal to me so much. I'm reading the book,(driver), by it's cover.

I have a 900 driver and the 2016 EZ driver. With some recent physical problems, I'm using the EZ driver because it feels lighter to me and has a senior shaft.

Instead of my usual 220-230 yard drive, (provided it's well hit), I'm barely able to knock it out 200 yards right now. For the first time in my life, I'm unhappy with my distance off the tee and a new driver with that kind of assistance would be a welcomed change.  Of course, I'd prefer to get my body fixed first, but at 68, I am seeing a difficulty in hitting greens from farther away due to shorter drives.

Keep telling us more...

What you want is an inconsistent ball striker to see how it holds up for the average player ;)

Does the St 180 have a neutral face angle? Or is it closed or open one degree. I do not need any encouragement to hook the ball because when I miss I hit it near the toe. Golfers on the fairway left of the tee keep yelling 12 and 13 letter cuss words at me.

Would a stiffer tip shaft reduce the spin on toe ******?

Again I hit this club and really liked it. It will take the pepsi challenge with sub zero and M1

Here's some test data from the morning with David Dixon.

Can see he was tweaking the JPX900 a little left.  The ST was a lot straighter - even with a little cut spin on it, was flying with less backspin (which you wouldn't expect from that cut).  

In summary - went from a slight pull draw to a slight cut without losing any yards.  For a tour player - that's what they're looking for.  The face of his 900 is actually now a little more lively than it was when new....gets a little more flex with use.

That's just first test - but i found the whole thing quite interesting.  David wasn't expecting or askjng for an extra 30 yards - he left pretty happy with a more predictable flight.
