The Mizuno Pro Fli-Hi might be my favorite driving iron

When I visited The Foundry, Mizuno Golf’s R&D and Fitting headquarters outside of Atlanta, I picked up one of their new Pro Fli-Hi utility irons.

It was already built into the mounting bay with a Ventus Black HB axle. Basically I fell in love with the club.

There’s just something about the Fli-Hi that makes it one of my favorite irons on the market, if not my #1. 1. I spent some time on the course with the Mizuno team hitting it on a tricky par-5, and it certainly showed its skills.

Let’s talk about why I think this is special.

The Mizuno Pro Fli-Hi has been at the top of the list for me for a long time. Even four or five years ago, when I worked at a national club fitter, the Fli-Hi was very popular in the bays; but it has always been for a more specific customer.

The Fli-Hi is probably the best option for the top player who wants more heat from a swing iron but doesn’t want to sacrifice looks. There are a lot of really good rolling irons on the market, but not all of them handle the look very well.

The newest iteration of the Fli-Hi has gone the extra mile to make sure it looks good behind the ball. Not only have they given the shape some very nice snaps and tacks around the edges, along with a very nice transition from the bushing to the front edge that protects the visual offset, but they’ve also changed the finish.

They’ve usually had darker finishes on the Fli-Hi in hopes of creating a more compact visual, but this latest iteration just looks… cleaner. The new Black Ion finish is reminiscent of the Mizuno Pro line of irons; Nice and clean, with a bit of shine for a more premium player look and by going dark over silver or chrome, it looks even smaller.

They’ve also done a very cool interior design trick with the topline of the club to reduce its size. They are using what is called an ‘Offset Face Weld’ which allows them to place the weld on the inside of the upper face gauge. On the downside, the weld is away from the face, which allows the face to flex more and create more ball speed.

Make no mistake, the iron is still a great utility style design, but Mizuno’s time and care to carve the shape into something every player can fit in their bag is evident.

The thing I love most about the Mizuno Pro Fli-Hi is how workable and versatile the club is. It is also very hot. I remember when I got the stocks built for testing early on, I was hitting lofts with the 4 iron marked close to 240 yards. I actually sent my friend at Mizuno a text saying “What should I do with a 240 yard iron?” to which he laughed and replied, “I’ve never heard anyone complain about a car iron going too far.” Fair point.

The ball speed and forgiveness of the larger COR area make for a fantastic tipping option, especially if you can afford the elevated 2-iron version of the Fli-Hi. It’s not just a stinger toy, which is my beef with other utility irons on the market. The Fli-Hi of a club can be hit up, it can be hit down, and it’s very easy to produce a great draw with the club that helps promote release when you need it.

My favorite part, though, is how good it is off the ground. I like to hit hybrids and irons; I’m not a huge wood player, so having something I trust off the fairway is massive. If a driving iron or hardware is going to end up in the bag, it needs to prove it’s not a one-trick pony.

You can see in the video that the Fli-Hi does everything I want it to do. I was able to hit a low tee on the same hole that I hit a high draw over a very tall tree. Both shots were on command, doubles. If that doesn’t indicate the usability of the Fli-Hi, I’m just not sure what would.
