Pros: Exceptionally long and forgiving players irons. They have thinner top lines, less offset and shorter blade lengths than TaylorMade’s RSi 2 irons, and feel noticeably softer at impact.

Cons: Performance is about the same as TaylorMade’s RSi 2 irons.

Who they’re for: The PSi irons target golfers with handicaps from 0-13 who want more distance and forgiveness from their irons.

The Review

Performance is a relative term in iron design, particularly for the amalgamous category of clubs called “players irons” that TaylorMade’s new PSi irons occupy. Some players irons promise better performance in the way of more distance and forgiveness, while others boost the ability of golfers to manipulate trajectory.

TaylorMade_PSi_irons_4_side_angle
The PSi long irons (3-7) are cast from 431 stainless steel. The short irons (8-PW) use 1025 carbon steel forged club hosels/faces, which are welded to 431 stainless steel bodies.

TaylorMade’s PSi irons seek to bridge the gap between those two types of irons, with a revamped construction that maintains the performance that made TaylorMade’s RSi 2 irons a leading performer in our 2015 Gear Trials: Best Players Irons list, while addressing the look, feel and size concerns that led golfers to consider offerings from other companies.

To test the PSi irons, we took them to the Launch Pad at Carl’s Golfland, where its team of Trackman Master Club Fitters hit them against TaylorMade’s RSi 2 irons. Both irons were tested in their stock configurations, with standard lofts, lie angles, and S-Flex shafts. For the PSi irons, the stock shaft is KBS’ C-Taper 105, while the RSi 2 irons used KBS’ 105 shafts.

Trackman tested outdoors. Results were normalized.

If you don’t speak launch monitor lingo, know that the results above are quite similar. So chances are, if you’re playing a set of RSi 2 irons and decide to purchase the PSi irons, you’ll see similar results as well. But there’s a lot to the PSi irons that won’t show up in launch monitor testing.

First of all, the PSi irons look different than the RSi 2 irons — not radically different, but different. The top lines are thinner throughout the set, and the composition is more progressive. What that means is that the long irons are comparatively larger than the rest of the PSi irons.

If you’re coming from a set of RSi 2 irons, you’ll notice that the size of the 3 and 4 irons is about the same, but the PSi mid irons and short irons have progressively shorter blade lengths and less offset. These changes will fit the eye of better golfers, especially those who want top-level distance and forgiveness from their long irons, but don’t need as much help with their scoring clubs. The change should help golfers hit the specialty shots they need from short range to setup more birdie chances.

TaylorMade_Hybrar_PSi
A material called hybrar is mechanically lodged against the faces of the PSi irons to remove the undesirable vibrations that are typical of irons with extremely thin club faces.

Maybe the most important difference between the two sets of irons is the sound of the PSi irons at impact. They use a new multi-material Dynamic Feel System as part of their construction that creates a softer, quieter sound at impact that golfers tend to equate with better feel and more control.

Something particularly interesting for golfers torn between TaylorMade’s PSi and PSi Tour irons is a new TaylorMade design initiative, which was aided by a new Speed Pocket — a handle bar-shaped slot in the sole of the irons. The Speed Pocket was moved farther forward on the sole PSi irons, and cuts into the cavity of the irons. It creates a launch angle that’s roughly the same as the smaller, fully forged PSi Tour irons, which will be the irons of choice for many of TaylorMade’s PGA Tour staff players.

TaylorMade uses Speed Pockets (3-7 irons) and Face Slots (3-8 irons) to improve the flexibility of the club faces, which create more consistent ball speeds on shots contacted across the face.

For the first time in recent memory, however, the combination of the more forward Speed Pocket and the desire to match the launch angles of the PSi and PSi Tour irons resulted in a set of irons that uses weaker lofts than its predecessor. While the PSi 7 iron is 2.5 degrees stronger than the PSi Tour irons, it’s 0.5 degrees weaker than the same RSi 2 club.

TaylorMade uses 10-gram tungsten toe weights in the PSi 3, 4 and 5 irons to lower CG and improve MOI, leading to higher-launching, straighter-flying shots.

PSi Specs

Another important upgrade for PSi is TaylorMade’s expanded custom shaft options, which allows golfers to upgrade to many of the most popular, taper-tip steel shafts at no extra cost. This is made possible because of TaylorMade’s decision to produce both taper-tip and parallel-tip versions of the PSi iron heads, which makes it easy for golfers to order combination sets of PSi long irons and PSi Tour short irons.

Keep in mind, however, that the tech-laden PSi irons will fly considerably farther than the PSi Tour irons, and loft adjustments could be needed to either the shortest PSi iron or the longest PSi Tour iron to create consistent gapping.

The Takeaway

TaylorMade_PSi_irons_Takeaway
Eight-piece sets of PSi irons sell for $1099 with steel shafts, $1199 with graphite shafts.

The PSi irons create outstanding distance and forgiveness, in line with TaylorMade’s award-winning RSi 2 irons, but offer better looks, feel and expanded custom options. For that reason, they’re a top choice in the players iron category for golfers who want more yards, as well as better players who want to explore the possibilities that TaylorMade’s most advanced irons to date can bring to their games.

  1. Best set of irons I have hit in a long time. Nice fit between players and GI. I play off an 11 and these fit me perfectly. I should get a backup set just to have once I wear these out.

  2. So everyone is gripping about a review on a “players club” not having enough average golfers to test them. These clubs aren’t fur average golfers they are for low handicap golfers. 4 and below. Sure go ahead and get these based on not having data for an average golfer and not having a high enough swing speed. Never hit the center of the club face twice with the same club in the same round. Then gripe about not being able to hit a green with them and needing 5 wedges. But you’ll have the same clubs in your bag as Jason Day so that’ll count a lot when your paying off to everyone in the 19th hole.

  3. It seems like TM is always searching for that iron that will be a game changer. I just don’t see it happening. In the “players irons” category, IMO TM has been passed by Cobra now, let alone Titleist and Ping.

  4. I hit them, great performance. They are just too ugly though, very Plain Jane cheap looking decals on the back…..looks like a proto-type waiting for a real design.

    Again, they perform well though.

    • Thanks for the comment, Billy. Our testing results are simply meant for head-to-head comparison purposes. We’re not saying that these are optimal numbers, and in this case these testers were not fit for these clubs before hitting them.

  5. I’m being put-off by the club reviews on this site. They seem like ego-stroking wastes of time for the average golfer (even for the tour pros at times).

    Take for example the 7-iron hit here by golfer #1: A 204 yard carry with a ball speed of 133mph. The tour averages are 172y and 120mph, respectively, according to Trackman. That’s 32 yards or almost THREE CLUBS farther than the average tour pro. Now the 3* less of average loft might have something to with that but honestly how many golfers are averaging 130+ ball speeds and maintaining any sort of strike consistency.

    The only thing bringing these numbers down to earth is the 3000rpm less of average spin and ~20* of decent angle compared to the pros. The landing angle and spin numbers are on par with the pros average 5-WOOD! Good luck holding any sort of green.

    They should offer these clubs in a set of 3 clubs and give you the rest in a coupon toward the 5 wedges you’re going to have to carry.

    Until you get someone that isn’t besting TOUR AVERAGES across all clubs I’m voting shank on every review.

    • Huh? You start off saying the test subject wasn’t fair. Then you start going on about too many wedges.

      1. The lofts are weaker than prior – that’s stated. So that reduces the loft causing the too many wedges problem.

      2. What does less ball speed mean to a review? It doesn’t impact anything, other than show you lower numbers. In fact – reviews like this are pointless other than pictures and stats about the physical measurements and maybe opinion on look and feel because everyone produces different numbers and you shouldn’t even reference those charts.

      3. It’s still useful if you’re intent on reading it because it gives a comparison between an older set.

      I’m really not sure what your beef is. It’s not 3 clubs better, it’s roughly 2 clubs, or 1.5 clubs than a tour pro. And remember that’s an average. Lots can hit a 6i further – but you said it right – the lofts change the club – and that’s nothing new.

      Even if the reviewer produced similar ball speed to you-it doesn’t mean he/she would produce the same spin rate, angle of decent and launch angle – so I don’t see why you care so much about one factor when even if it was in your wheelhouse, the data is still basically irrelevant.

    • Then don’t read. I grew up playing forged blades that most golfers nowadays couldn’t get airborne. I couldn’t come close at my current age and swing speed.Equally these PSI irons are no longer a fit for my game. But I like reading about the technology. I’m not a car buff but I’m willing to wager that most subscribers to Road and Track will never drive let alone own a Lamborghini. Lighten up.

    • Well, its really a 6 iron. However, that is still a long way for a 6 by most people’s standards. Would be nice to have an 8-12 hdcp testing these clubs alongside a wrxer-pro.

  6. i hit a 7i last night at golfsmith. the ball flew far…really far. consistently 15ish yards farther than may titleist 7i. then i started looking at the clubs and specs, shaft was 1 inch longer and loft was much stronger. so not really an apples to apples comparison. the ball felt really soft coming of the psi face almost weirdly soft and im not sure if i liked it or not. but these do as advertised, they are long. i didnt hit them enough to get a gauge on forgiveness.

  7. As for other Trackman iron tests done in the past couple of months, really appreciate the effort to put actual comparison numbers up…. But same problem as before, tester one in particular has a very high swing speed but launches it very low and with far too little spin (6000rpm with a 9 iron, normal recommendation would be 9000).
    If there was any chance for one or two testers to be used who were more ‘regular / average’ type players the test results would be more indicative for more of us.
