Callaway’s new XR OS irons and hybrids



Callaway’s XR irons and hybrids from last year (the standard models, not the “Pro”) were classified as game-improvement clubs, industry code for high-launching, forgiving clubs with big profiles and wide soles. The new XR OS irons and hybrids — the “OS” stands for over-sized — are made to be super game-improvement clubs. That means they’re the highest launching, most forgiving irons and hybrids Callaway has made to date.

Who is the new XR OS line for? Golfers who are either inconsistent or have slow swing speeds, and need the longest, easiest-to-hit irons and hybrids possible. If you had interest Callaway Big Bertha irons, or super game-improvement clubs from another company, these are for you.

So what makes the XR OS line more forgiving, and how exactly will they help your game?


Callaway’s XR irons, released in 2015, were the first generation of irons to utilize Face Cup, a Callaway technology used to improve ball speed across the face, especially on mishits. The new XR OS irons have an improved Face Cup. The second-generation design has thinned out areas around the perimeter, making those areas faster, and a sweet spot located lower on the face where most high-handicap players tend contact the ball. The improvements give the XR OS irons higher ball speeds in the areas where golfers want to hit them (low and in the center of the face), as well as where they hit them when things go wrong.

Many irons with extremely thin and fast faces can sacrifice feel due to the significant vibrations that can occur from such designs. To reduce those vibrations, Callaway engineers put TPU between the face and the cavity — called a “snubber” — ultimately improving sound and feel.

For a higher launch and better contact, Callaway redesigned the soles with a trailing-edge bevel. It has the two-fold benefit of moving the center of gravity (CG) lower and more rearward, as well reducing turf interaction to help golfers make cleaner contact for longer-flying, more consistent shots.

Another problem that high-handicappers and slow-swingers face is differentiating the distance their long irons fly. For instance, maybe their 3, 4 and 5 irons all carry within 5-10 yards of each other. That hardly justifies the need to have all these clubs in the bag. But with the XR OS irons, Callaway has added loft and length to the longer irons, helping golfers spread yardage gaps and establish proper spacing throughout the set.

Here’s a look at the progressive loft-gapping, showing the differences in lofts between irons throughout the set: 4-6 irons (3 degrees of change), 6-8 irons (3.5 degrees), 8-9 irons (4 degrees), 9-PW-AW-SW (5 degrees). All of the lofts are below:

  • 4-iron: 22 degrees
  • 5-iron: 25
  • 6-iron: 28
  • 7-iron: 31.5
  • 8-iron: 35
  • 9-iron: 39
  • PW: 44
  • AW: 49
  • SW: 54

The spacing makes creating a combo set more seamless since yardage gaps are more identifiable, according to Callaway.


The XR OS hybrids, like the irons, are the highest launching and most forgiving option in Callaway’s stable of hybrid offerings. They feature wider soles and larger profiles, and utilize the latest Hyper Speed Forged Face Cup for high ball speeds across the club face. They also have a low and back CG, a high moment of inertia (MOI) and increased draw-bias, making them easier to get airborne and turn over compared with the original XR hybrids.


A new sole, which Callaway calls “Dual-Keeled Utility,” is large, but is said to reduce ground contact by 50 percent, improving the versatility of the hybrids.

The XR OS hybrids (3, 4, 5, 6 and 7) come stock with a Mitsubishi Fubuki AT 60 shaft, and are available Jan. 22 for $219.99. The XR OS irons will be available on Jan. 22 in both steel, graphite, and combo-set offerings.

XR OS Pricing

  • Steel: $799.99
  • Graphite: $899.99,
  • Steel Combo Set: $899.99
  • Graphite Combo Pricing: $999.99
  • Available Irons: (4-SW)

    Unbelievable. Go back 15 years ago, and their irons and hybrids look exactly the same as these. What a joke. Take a hint from titleist or ping and release clubs every other year.

    Hard to believe an OEM got the loft gapping backwards…I do not know who is testing this stuff, but it is not the average golfer. How do they think reducing lofts in the lower irons increases yardages between the clubs. And increasing shaft lengths just guarantees poorer results for average golfers who struggle with lengths longer than 7 irons, let alone lengths for a 4 iron (with a 3 iron loft) that is longer than 1 irons used to be.

      These types of clubs are designed with the novice golfer in mind. These golfers are not likely to be as consistent as the mid-low handicapper; they are more likely to be impressed and excited by the distance gains they get from lower lofts and longer shafts. They probably aren’t going to hit these clubs any more consistently than their half-an-inch shorter counterparts, so why would you focus on length and lofts for consistency when you can design a club with game-improvement tech and focus on distance? The vast majority of average players want to see distance gains.

        Except they would get likely get more distance with higher lofts and shorter lengths in the lower/mid irons as longer lengths only help if it doesn’t result in a worse impact. I reduced my lengths to improve my ball striking to great success when I was a mid-high handicapper and may just keep them shorter as I move forward. I was also experimenting with my lofts and decided to increase them 1-2 degrees to have 4 degree differences and was pleasantly surprised by my rather large distance gains (better ball flight for my setup) when I was willing to accept some yardage loses based on the current “wisdom” of the OEMs. For the longest time a 4 iron was 38 inches long and 24/25 degrees because the average golfer just couldn’t hit longer shafts or less loft with much success – at least until the marketing departments could show increases with an Iron Byron machine, which I am not. Besides, all I really care about is that there is only 3-4 months till the 2016 golf season! Cheers.

Wunder: I’ve hit THESE new drivers this year…and this is what I think



During this lockdown, I have done quite a few “Friday Q & A’s” on my IG, and one of the questions I get asked constantly is “have you hit this?” That, and “whaddya think?”

So, in the spirit of organizing my brain, it seemed like the right time to share what new drivers I have actually hit this year…and this is what I think.

Now, it needs to be said that there is a lot of new gear out there, but, to be honest, I’ve only actually hit a select few enough to actually build an opinion. “Enough” in this case is at least 20 balls. Some of these sticks I tested during our pre-launch preview with the OEMs, at the PGA show, a friend has one, or I actually have it in the bag.

Here we go.

TaylorMade SIM

Setup tested: SIM 9 @8.25 w/ Mitsubishi Chemical Kuro Kage XTS 70TX

LOOKS: The best way to describe how SIM looks behind the ball is “comfortable.” TaylorMade has always made drivers that just look correct. The lines are clean, the shape inspires playability, and I dig the paint job. They hit a home run with this one for sure.

FEEL: Best sound out there in my opinion. Heavy, dense, and if you get one dead-nuts center, it lets you know. The feel at contact is just as TaylorMade drivers have always done, center strikes feel like Thor’s hammer and mishits don’t kill your good vibes.

VS THE M5: I get asked this a lot. I loved the M5. Still do. To be honest the two drivers data wise were legit apples to apples. The only difference is my stock shot with M5 was a low spin straight ball and with SIM its a slight draw with a touch more spin and slightly lower launch. I prefer that.

OVERALL: In my opinion, the TaylorMade SIM is the cool kid in high school for 2020. Last year it was F9 followed closely by M5. TM knocked it outta the park on this one.

TaylorMade SIM Max

Setup tested: Sim Max 9 @8.25 w/ Mitsubishi Chemical Kuro Kage XTS 70TX

LOOKS: It has a bit more of a longer face at address, which makes the head appear shallow which inspires a bit more confidence to turn it over. That’s the main thing I noticed with MAX. Other than that its a tried and true TM shape.

FEEL: Like its sibling, it has a nice solid hit audibly at the impact. So, overall its apples to apples with SIM. However, due to the front weight missing on the MAX, the actual strike doesn’t feel AS meaty as SIM. Not a negative necessarily just something I noticed.

VS M6: Both of these sticks I launched a bit too high versus the weighted versions. That’s why they never got any serious consideration to actually put in play.

OVERALL: As a high launch, more forgiving option, it’s an ace.

Callaway Mavrik Sub Zero

Setup tested: Sub Zero 9 w/ Mitsubishi Chemical Tensei Blue AV 65TX

LOOKS: To my eyes, the newer versions of the Callaway drivers have looked a bit more compact than its competition. To me, this always looked “low spin” for whatever reason. The Mavrik has the same shape which is good.

FEEL: They really fixed the sound. The Epic Flash sounded like a pop can to me, and the Mavrik Sub Zero sounds like a sledgehammer. The good thing here is the sound now matches up with what the hit feels like. I think the Mavrik is the best feeling driver Callaway has made since Epic.

VS EPIC FLASH SZ: To me, a complete improvement on all fronts. Sound, feel, and performance for me were all substantially better. Now I must say that the Epic Flash Sub Zero was a great driver, I always got great numbers out of it, but the sound took me out of it. I’m sure there isn’t that much difference audibly between the two, but in this game, even something minor can represent so much. Sound to me is huge.

OVERALL: In all honestly, I haven’t given a Callaway driver a real hard look to actually put in the bag since Epic. The sound got louder wit Rogue and Epic Flash. The Mavrik SZ  however is a fantastic driver and will def get some more testing out of me.

Cobra SpeedZone

Setup tested: Cobra Speed Zone 9 @8.5 w/ Fujikura Ventus Black 7X

LOOKS: The F9 was a winner on all fronts. The only critique I had was optically it looked like the driver was a little too fade biased. The SZ with its milled in top line gives it softer look at address and for me, softer lines mean more workability, just what my eyes tell me.

FEEL: As with F9 and the earlier mentioned SIM, the Speed Zone sounds EXACTLY how a driver should sound. It has a very heavy hit audibly and that’s across the face. I love the sound of this driver.

VS F9: Apples to apples, it’s the same. Beyond the optics, it feels, sounds, and performs like the F9. Not a bad thing though, the F9 was the driver of 2019 in my opinion.

OVERALL: Nothing wrong with repeating an already awesome driver. SpeedZone will stand up to anything out there. If I’m being fair, I think F9 elevated things in 2019, and this year the competition caught up to it. Changes nothing about how good this driver is.

Cobra Speed Zone Xtreme

Setup tested: Cobra Speed Zone Xtreme 9 @8.5 w/ Fujikura Ventus Black 7X

LOOKS: Like the other drivers in this higher MOI category, it looks a little longer heel to toe.

FEEL: No different than the SpeedZone, sounds great, the impact is solid across the face, and even thin shots feel solid.

OVERALL: The Xtreme is the sleeper hit of 2020 and I’ve heard the fitters love this thing. It’s by far the easiest to hit and overall good time of any driver on this list. Is it longer? No. But is it Xtremely (no pun) playable and competitive? Hard yes. It’s a blast.

PXG Proto

Setup tested: PXG Proto 9 w/ Graphite Design Tour AD IZ 6 TX

LOOKS: Slick. Like all PXG gear, the look is there. The matte crown and elegant lines make it very pleasing optically. I also appreciate that although it’s designed to look high tech. The lines inspire playability, and who doesn’t love a driver that looks like a stealth bomber?

FEEL: I only hit about 20 balls with the PXG Proto in the short time I had with it, but, wow, did this thing surprise me. The sound oddly enough is a bit higher-pitched than the others on the list but for whatever reason, it’s not a distraction. It actually adds to the experience of the hit. I typically detest that, but this sound matched up with the solid hit I was getting. I’m not sure if this is the final version since its a limited tour proto but what is happening is definitely interesting.

VS GEN2: It’s just better. Feels better, sounds great, more playable across the face. The Gen2 did one thing better than everyone else, it destroyed spin. The problem I had was control. The PXG Proto is still low spin but with the new 4 weight system (no intel on the tech yet) seems to add quality launch to the low spin profile and puts the player in a situation where very few to any sacrifices are made.

OVERALL: I was a fan of Gen2. No doubt. But it never flat out beat M5, F9, or SIM. The Proto has elevated PXG’s driver game. I don’t think its a matter of whether or not the driver stands up with the irons, I believe PXG is on the right track to having a driver that eliminates any “yeah, but…” to the conversation. That’s a huge leap since Gen1. These guys are trending hard.

I hope this was helpful.

Should I move to heavier iron shafts? – GolfWRXers have their say



In our forums, our members have been discussing the strategy of moving to heavier shafts in irons. WRXer ‘Z1ggy16’ has been making swing changes lately, and the transition has been most challenging for his iron play. ‘Ziggy16’ says:

“Been making some swing changes lately, most notably working to really shallow my club into the downswing. I’m finding that I’m doing this well with my heavy wedge shafts and driver, but I’m struggling a bit in my irons. My strike pattern with my wedges is pretty good, but the irons are a bit all over. Driver is 80g raw, wedges are 132g raw, irons 120g raw. I don’t think I want to go any stiffer, but is there a chance I’ve “outgrown” this weight and need to move to something a bit heavier to help keep these feels going through my set? No idea what swing speed is at this point, but my 7i is normally a smooth/comfortable 175-180 for me.

I really like the feel of my Accra Tour Z Xtreme 475 and my S400’s in the GW-LW. I’m kind of leaning maybe soft stepping modus 120TX or X100’s.. Heck maybe even S200 straight in? Normally I’d just get a fitting, but with Rona still going around, I’m not than keen on it. 2020 is the year of the self fit for me. FWIW, I used modus 120TX 2xSS in my GW & SW last year and that was pretty good feeling. Perhaps a touch too soft… they seemed to really whip/bend hard when hitting from the rough on full swings.”

Our members discuss whether they feel a switch to heavier shafts in the irons will have the desired impact.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • Pepperturbo: “You’re not alone. Regardless of age, some of us swing better with heavier shafts. I went from 70g driver and 85g 3wd graphite shafts to 58g Ventus shaft in driver and 70g Ventus shaft in 4wd. In irons went from 130g X to 120g 6.0 PX steel shafts which lasted about fifteen years. Then last year made another downward weight change to Steelfiber (steel & graphite) 110g Stiff shafts, lightest I have ever played. Keep in mind as you transition, changing shaft weight is not the only answer. Increasing swing weight can make up for shaft weight. Though I really like them in 6-3i, not thrilled in SW-7i, so just ordered heavier Steelfiber i125g shafts for my PW-7i blades.”
  • Jeff58: “As someone who has gone through and continues to work on what sounds like a similar situation, your ideal iron shafts will likely change. Where they change to isn’t possible to predict with any degree of accuracy. Don’t change your current irons without knowing. It’s frustrating, expensive, and you won’t have any clubs while they’re being changed out. Instead, get a single club from dealsandsteals or similar and experiment with that. Also, the only relevant experience is outdoors under your actual turf conditions. Indoor and mat use can be grossly different.”
  • Red4282: “Just depends on your tempo and load and preferences tbh. My numbers are about identical to yours; I play 77g in the driver and 125 in the irons. I don’t think I could go lighter than 125.”
  • gvogel: “I have a set of hickory clubs. Of course, hickory shafts are darn heavy, maybe 150 grams or so. I probably hit straighter shots with the irons, and particularly hit better shots with the niblick (wedge). Driver and fairway woods, not so much. That might be a stupid insertion into an intelligent thread, but heavier goes straighter, lighter goes longer. You can go heavier, and it helps in transition, but don’t go too stiff.”
