Cleveland 588 MT and TT irons: Editor Review



Pros: The higher-launching, more forgiving MT irons and lower-launching TT irons blend together nicely to allow a player to mix and match a set. Both sets have better performance on mishits than most players irons, and a solid feel on center strikes. There’s real springiness to the forged faces — especially the MT irons, which perform like mini hybrids.

Cons: Less workability than many players irons. Blade enthusiasts won’t love the thick top lines of the MTs, and the TTs are a bit bulky for a “tour” iron.

Bottom Line: The 588 TT irons are a legitimate step forward from the 588 Forged line, adding distance and performance on shots struck both on and off center. Most players will sacrifice the modicum of playability for irons which look and feel this good. The opportunity to add more forgiving hybrid-esque long irons (the MTs) is a significant advantage, as well.


Following up the 588 Forged CB and 588 Forged MB irons, and several years removed from the Black Pearl era of Cleveland Irons, Cleveland Golf released the 588 MT (medium trajectory) and TT (tour trajectory) irons for 2013.

The company intends for the irons (as well as the super game-improvement Altitude series) to be fully interchangeable with one another so golfers can, as Cleveland says, “build the perfect set.” Thus, I reviewed the 3 iron (19 degrees) and 4 irons (21 degrees) from the MT line, in conjunction with the 5 iron through pitching wedge (44 degrees) in the TT line.


The MT irons (above) are used by several of Cleveland Golf’s staff players, including Keegan Bradley, Charlie Beljan, David Toms and Graeme McDowell (Click each player’s name to see a WITB with full specs and photos).

Both the MT and TT models feature multi-material vibration-dampening inserts that are intended to provide a more consistent feel across the club face. Both models also are equipped with Cleveland’s Forged Face Technology, by which a forged face is essentially inserted into the golf club.

The MTs feature full-hollow construction, which creates “advanced internal weighting that adds forgiveness and promotes a lower, deeper center of gravity for optimal launch and … distance.” The line also features progressive blade heights, moving from shallower in the long irons to taller in the shorter clubs, while the TTs have a constant blade height and a variable blade length.


The club’s forged face insert is something of a trampoline, and initial ball speeds are quite high. However, the company has improved its way to a potential fault, as the pitching wedge is almost too hot to use around the green.

Between the hot face and the stronger lofts, players will likely be picking up a few yards with each iron. Happily, trajectories shouldn’t be markedly lower, due to the the CG and undercut design.


Both the MT and the TT are remarkably forgiving: Mishits fly father and straighter, and that isn’t just talk. Unless you need to work the ball like Bubba Watson, you’re not going to suffer from the decrease in playability compared to, say, previous 588 Forged models.

The 588 MT irons really get up in the air, which will be a benefit for the vast majority of golfers. However, better players will want to stick with the TTs as their long irons.

The TT’s rounded sole and compact design, in particular, make it a versatile and functional club from the rough, and it’s likely to outperform competitors from the territories outside the fairway due to both sole design and a face that ensures maximum distance on even the least convincing strikes of the golf ball.

Looks and feel

In the longer irons, the MTs are reminiscent of the old Mizuno Fli-Hi: long body and wide sole. Depending on playability and personal preference, this may be confidence-inspiring or annyoing. The TTs feature a substantial cavity, but it isn’t visible at address. As mentioned before, the top line of the clubs is wide, and is of comparable width to the TaylorMade RocketBladez irons.


The 588 MT irons have wider soles than the 588 TT irons, which lowers the center of gravity for a higher launch, but decreases versatility from the rough. 

A similar aesthetic to the RTX CB wedge models is evident on the rear of the club, and there are suggestions of the 2008 Cleveland CG Golds/Reds in the design.

Cleveland’s claims about the vibration dampening effect of the insert held true, almost to a fault, as there was (not surprisingly) less feedback at impact than with most traditional players, although off-center strikes didn’t come with their usual sting.

The models demoed featured Cleveland’s Traction 85 S flex shafts, but a variety of options are available.


Additionally, the loft and lie chart is below. Predictably, the lofts are 3 to 4 degrees stronger than in the 588 CB irons and reflect the industry imperative of strengthening club lofts.


The Takeaway

The elephant in the room with this year’s iron offerings for better players is Taylormade’s RocketBladez. So, this year, Cleveland moved away from the traditional look and construction of their 588 MB and 588 CB irons towards polymer and forged faced inserts.

The death nell of the forged iron may have sounded years ago, but with the adoption of the larger, longer-flyinh irons by the world’s best players, it seems that the “players iron” of today is a club that would have been positioned between players club and game improvement iron five years ago.

It is this spot that the Cleveland TT irons (and to a lesser degree, the MT irons) occupy. And if you’re anything other than the staunchest of blade purists, the Cleveland TT is worth your consideration. Likewise, if you aren’t contending for your club championship, a mixed set of the MT and TT irons will provide key benefits throughout the bag.

Another point of consideration in comparing Cleveland’s crop to their obvious competitor: the MT and TT lines both sell for $699, a price that’s below most of the competition.

    So does this mean I can buy (if I want) only 4-7 of MT and 8-GW of TT?

    I bought the 588 MT’s after careful consideration of Callaway and Taylormade and I am glad I made the purchase. I have the 4 – DW in my bag now and could not be happier. It took a little while to get used to the higher irons and getting them to fly like my past clubs that I played for 10 years but after a few slight adjustments, I can always count on the yardage and flight pattern that is now a slight draw rather than a constant fade.
    The workability on these clubs is also surprising as it is a forged face rather than a full forged club and when properly hit, it will do what you intended it to do. I have never owned Cleveland clubs before but these have me sold for many years to come.

    Hi all, I have just purchased these clubs. They’re bloody brilliant!! I have just come back to golf four months ago after not playing much other than the odd social game for near on 20 years. Got the wife into it, joined a club here in Sydney Australia and back in the week to week competition.

    Issue was I had old clubs, Bridgestone Rexceeds in fact. I found I had clubs that were not performing, very unforgiving and just not cutting anymore. I was being outhit by golfer I thought were worse golfer than me for distance. I researched the internet until could not do so anymore. Too much information but I did learn that I would benefit from new stick regardless and get better distances and for sure better control, two things I needed to improve my handicap.

    My handicap was given back to me was 20. Disappointing considering in the heady days as a teenager I played off 13 so not hitting my irons was frustration.

    I went to buy new clubs and I listened to current golfers who said, YOU MUST go and hit them, DO NOT buy them off the rack or internet. Thankfully I listened. First I bought a driver, a Callway Razer Fit 9.5 with stiff shaft. Great driver, hitting it miles. Bought a new Callway bag for it and my old clubs.

    Now, being a little OCD I wanted everything to match so when I went to try the different irons, I wanted to buy the Callaways but tried them , the Clevelands which I ended up buying and the Pings and the Mizuno’s which came second. I rated Pings third and Callaways 4th. Still does my head in as an old school golfer I wanted everything to match but now realise that it’s not important.

    What I did learn though from Cleveland was that not only do they feel incredibly nice to hit and they have great feel, but you can match the TT and MT clubs, I bought 4-6 in MT and 7-S in TT. Took some convincing but I am one of the converted. I also though that ad was a complete embarrassment when I saw it and I had even made up my mind I wasn’t going to buy those clubs because of the ad but when I tried them, I was sold. BTW, the ad is actually right on the money.

    I now have the clubs, they are great for OCD people too because they look the same yet you get the forgiving MT’s on the long irons and TT’s on the short irons.

    Seriously since having these clubs a month, I am heat seeking the pins on par 3’s and getting incredible accuracy and distance on long irons.Now I am hitting past those guys I thought I should have been hitting past all along. I also noticed that these clubs are incredible for forginess becaseu on the shots I have hit badly, I am astonished how they ended up. Already shot a 44 point game and my handicap is down from 20 to 17 already in one month! I swear by these clubs if you are interested to know and if you compare, you will see the difference between their peers, especially the feel off the club and I would say they are going to great for me as I lower my handicap because I will not need to replace them. When I asked why they felt so much better I was told it was because fo teh forged face. Now don’t take my word for it nor necessarily believe this, but there is something that makes these clubs that bit better, and maybe this is why.

    Next challange………….. need some more wedges in the bag!! Question is, which brand? 🙂 back to shops we go for more road testing I think.

      Terrific and enjoyable comment from John Davis. Thanks, and welcome back to The Game. I am curious. What shafts were recommended for you and which model did you choose. Standard Traction 85 shaft seems awfully light and with a high launch profile.

      Has anyone else demo’d, bought or custom ordered the TT and MT irons with a different shaft than the off the rack shaft?

        Hi…bought a custom set of Mt 4,5 and TT 6-D wedge in KBS Tour shaft plus 588 forged in 54 and 58…fantastic combo..better control and distance. I chose the KBS as I had them in my old TM R9s. Lovely soft, crisp feel when hit on the sweet spot.

GolfWRX Spotted: Titleist TSi hybrids seeding at The American Express



To say Titleist has been having success with its TSi metal woods and T-Series irons would be an understatement. Just this past week, the TSi Series drivers were the number one driver at The Sony Open, and in more than one event during the 2020 portion of the PGA Tour season, they swept all major equipment counts from drivers all the way to wedges and putters.

Now, building on the success of the TSi series, Titleist has just launched its newest TSi hybrids on the PGA Tour at the American Express in La Quinta, California.

TSi2 hybrid from address

Titleist looks to be following the design principles of the TSi series with the TSi2 being a wider-soled hybrid intended to help increase launch while the TSi3 is more compact and also included the same SureFit CG (center of gravity) track that can be found in the TSi3 driver and fairway woods.

TSi3 hybrid sole

The hybrids will also continue to utilize the SureFit adjustable hosel to fine-tune lie and loft and help golfers dial in ball flight.

We don’t have the full technology story yet, but based on the success of the previous generation hybrids both on tour and with regular golfers, we can expect Titleist has pulled out all the stops to achieve maximum performance.

See what golfers are saying about the TSi hybrids in the forums.

GolfWRX Spotted: Aldila Ascent shafts at The American Express



The PGA Tour is back on the mainland and on the west coast this week at The American Express being played at PGA West in La Quinta, California.

That’s not too far from Carlsbad where a majority of the OEMs in golf reside, which also makes it the perfect place to show off some of the latest technology and components to tour players—including shafts.

This week, we spotted the all-new Ascent shaft from Aldila, which judging from the finalized graphics, could be available soon in the retail market.

We reached out to Aldila and parent company Mitsubishi Chemical to get the details on the new shaft and what makes it different from others currently available on the market, and here’s what we know

  • The new Ascent shaft is designed to help golfers increase their ball flight apex while still offering lower spin performance and stability.
  • The shaft uses unique tungsten-infused prepreg to focus mass towards the tip which in turn improves ball speeds and stability while also maintaining feel.

The shaft also features what Aldila is calling an Impact Stabilization Zone—a section of increased stiffness, which, as the name suggests, helps stabilize the head towards impact. It is designed to pair with the heavier tungsten prepreg at the tip to create an active yet stable shaft that promotes launch while maintaining accuracy.

Shaft specs, pricing, and availability

We don’t have confirmation of the retail availability or the pricing of the new Ascent shaft from Aldila, but we do have the spec sheet, which gives some insight into the options that this shaft will be available in.
