Last summer I found a set of forged irons that progressed from cavity-backed long irons through muscle-backed mid irons to blade short irons.

Despite my low double-digit handicap -- and occasionally erratic ball-striking -- I hit these irons well. Thanks to a few rounds in which I pured nearly every iron shot, I convinced myself that I was finally moving beyond the need for any sort of true "game improvement" iron.

Then, as always seems to happen with us chronic double-digit handicappers, something began to go wrong. I'm not sure what exactly, but something small and imperceptible changed in my swing. I started hooking the ball again, and no matter what I tried, ball contact migrated more toward the toe of my club.

The question then became whether I would benefit from moving back to "game improvement" irons. I didn't want to give up the sleek toplines of my progressive set, or the feel and workability of forged steel. Never again would I go back to irons that look like skillets on sticks.

The answer, happily enough, arrived in the form of the new Mizuno JPX-825 Pro Irons. Marketed to players with 6-18 handicaps, the JPX-825 Pro Irons feature heel-toe weighting and a more reactive face, characteristic of typical game-improvement irons.

On the other hand, they also have a thinner topline than Mizuno's standard JPX-825 Irons (or any other game-improvement irons), a narrower sole, smaller clubhead size and Grain Flow forged steel, all of which combine for the look, feel and maneuverability of more typical "player's" irons.

How the Mizuno JPX-825 Pro Irons play

The JPX-825 Pros are sharp-looking, and, despite a somewhat more pronounced progressive offset (ranging from 0.106–0.176 inches) than my previous combo irons, they were easy to align. Likewise, the topline of the JPX-825 Pros are a touch wider than irons intended for low-handicappers, but they are not as bulky as comparable irons by, e.g., Callaway and Ping.

On the golf course, the performance of the JPX-825 Pros has been nothing but consistent. The forgiveness is almost startling: my off-center, toe-end contact now leads not to wicked toe-hooks, but rather gentle -- even controllable -- draws. And these occasional off-center strikes do not lose much, if any, distance. Recent rounds, during which I corrected the contact issue, have proven the JPX-825 Pros to be about 5-10 yards longer than my previous irons, too. So I feel like I can swing easier and get the same or better results.

The JPX-825s' workability was tested during my first round, when I found myself needing to hit a low, 160-yard semi-snap hook under tree branches and out over a pond to the green of the par-5 third hole of my home course. With my old blades, I knew I had the shot, but the JPX-825 Pros were so new, I didn't know how they'd perform. (Heck, I'd only taken three swings with them so far). But I figured, "What the heck? What's the fun of chipping out to the fairway?"

The ball rocketed out from under the branches over the pond, never more than 6 feet off the ground, and bent exactly as planned, toward the front-right flagstick, coming to rest in the frog-hair, just below the pin.


As for the feel, the JPX-825 Pros aren't quite as soft as more traditional forged "player's" irons. But they provide ample feedback to let you know immediately where and how well you've struck the ball.

Mizuno JPX-825 Pro Irons: The verdict

I cannot count the number of times I've hit the Mizuno JPX-825 Pro Irons over the past half-dozen rounds and thought, "Uh-oh." Yet on all but two occasions, the off-center contact that elicited this exclamation ended up far better than I had at first feared. And the fact that so little distance is lost on these shots is still a surprise.

These irons are as forgiving as any true "game-improvement" irons I've ever tested, yet provide feel and workability close or equal to most "player's" irons. Such is their quality that they have even been spotted in the bag of at least one PGA Tour player (Charles Howell III).

The JPX-825 Pros don't come cheap, with a typical street price of around $900, but if you're looking to upgrade from a clunky set of high-handicapper irons or finally give in to the occasional need for added forgiveness, these Mizuno sticks should be high on your list of options.

    I am proud to have switched From TM burners to the 825 Pro as advised by my low handicap golf buddy.. As a high handicapper fairly new to golf, I think these are the perfect "game improvement" irons. I do not buy into the whole GI concept with irons as once the club gives no feedback and does not penalize bad swings how is your game ever going to improve? With the 825 pro its just forgiving enough with tons of feedback. Truely an iron that will be a "game improvement" tool you will not out grow as your game improves.

        I could never get used to the PING offset. Hit the $1600 ANSER irons, nice but way over priced. The new G25 are in the 7-800 $ range and should be popular with the PING fans...I'll stay with these beautiful MIZZY PROS...Good luck in 2013 !!!!

    Nice review Joe. I was just fitted for these a couple days ago. I tested many other clubs and kept coming back to these. I've only ever played cast cavity back's and am so excited to move into a forged "players club" that offers some forgiveness. IMO these are the best looking clubs I've ever seen, and Mizuno's fitting process is really impressive. Can't wait to get them in play and start lowering my handicap!

    Just got my new Mizzy's. I'v had TM in my bag for 10 yrs.+. I'v lowered my handicap in recent years since I retired ( I'm a solid 10 and a decent ball striker). My local fitter gave me 825 PRO,Cally,New Bladze etc. etc etc...The Mizzy had a great sweet spot,forgiveness and looks that won me over !!! The quality of the Mizuno forging is unsurpassed and I'm now proud to have these great clubs in my bag....Your review is spot on....Joe
