I did this experiment because I am currently using blades after using game-improvement irons for a long time. And after a few rounds with the blades, I have found no real drop in performance.
Moment of inertia (MOI), a measure of an iron’s forgiveness, is as a selling tool for new irons, but I am not sure how much real improvement it is offering the golf community. My video goes a long way to show that maybe the way we’re thinking about fitting irons to our game is quite wrong.
Both the irons I tested in the video had stiff shafts. The Mizuno MP-5 (blades irons) had True Temper’s Dynamic Gold S300, while the JPX-EZ (game-improvement irons) had True Temper’s XP 95 S300 shafts. Both irons were tested with stock lofts and lengths.
On Spec: Talking about slow play
Ryan has guest Rob Miller, from the Two Guys Talking Golf podcast, to talk about slow play. They debate on how fast is fast, how much time should 18 holes take, and the type of players who can play fast and slow.

If Jurassic Park had a golf course, this would be it
I have had the good fortune of playing some unbelievably awesome tracks in my time—places like Cypress Point, Olympic, Sahalee, LACC, Riviera, and a bunch of others.
However, the Bad Little 9 is the most fun golf course I have ever played…period.
Imagine standing on the first tee of a 975-yard track and praying to God almighty you finish with all your golf balls, your confidence, and more importantly, your soul. Imagine, again, for example, standing on a 75-yard par 3 with NOWHERE to hit it beyond an eight-foot circle around the flag, where any miss buries you in a pot bunker or down into a gully of TIGHTLY mown grass.
I have played the BL9 twice at this point, with the first time being on a Challenge Day in November. It was cold, windy and playing as tough as it can. My playing partners Chris N., Tony C., and I barely made it out alive. I made four pars that day—shot 40—and played well. Do the math, that’s 13 over in five holes on a course where the longest hole is 140 yards.
It’s a golf course that makes zero sense: it’s punishing, it’s unfair, it’s crazy private, and on “Challenge Day,” it’s un-gettable even for the best players in the world. Rumor has it that there is an outstanding bet on Challenge Day for $1,000 cash to the individual that breaks par. That money is still yet to be paid to anyone…keep in mind Scottsdale National has PXG staff playing and practicing there allllll the time. To my knowledge, James Hahn has the lowest score ever at one over. That round apparently had multiple 20-foot par putts.
The Jackson/Kahn team which is responsible for the two big courses at Scottsdale National (Land Mine and The Other Course) were tasked with a challenge by Mr. Parsons: create a 9-hole course with ZERO rules. Take all conventional wisdom out of it and create an experience for the members that they will NEVER forget.
In this video, you will get a little context as to how it came together straight from the horse’s mouth, so I won’t get into that here.
I will end with this before you get into the video.
The Bad Little 9 sits in a very exclusive club in North Scottsdale, most will never see it. HOWEVER, what the idea of it represents is a potential way into bringing more people into the game, making it more accessible, saving real estate, playing in less time and having an experience. Hell, YouTube made short-form content a necessity in our culture. Perhaps the idea behind the Bad Little 9 will inspire short form golf?
Hot Drivers: What’s really going on!
Thanks to the R & A and Xander Schauffele, along with (allegedly) at least three other players we don’t know about yet having drivers test over the CT limit for speed, the golf world has exploded with hot takes on the subject.
Did the players know? Did someone else know? Are OEMs building fast drivers to trick the machine?
I’m not here to make hot takes, I’m here to talk facts and truths about how we got here and how Xander Shauffele (and potentially others) arrived at Royal Portrush with drivers over the CT limit.
First, let me make one thing straight, I don’t believe Xander, or any of the other players, had any idea their drivers were illegal/over the limit. Did they know they had a great driver that performed? Yes, but golf is a game of integrity and like life, in golf your reputation is everything; I don’t believe for a second they thought they were getting a distinct advantage against their playing competition.
How Does This Happen?
Modern driver heads are complex things. The tolerances that the OEMs and their suppliers work with are extremely tight—like aerospace industry tight—one engineer I have spoken to many times has said its actually tighter. You have extremely thin yet strong titanium, moveable weights, carbon fiber, and more working together in a complex geometry. They are built to launch golf balls up to 185 MPH all while maintaining flexibility so as not to explode on impact. It’s not easy to make a good one but the good ones make it seem easy.
A driver face will eventually wear out, its a fact. It can only take so many impacts before it will fail. The number it takes is generally very high, so high that many golfers will switch before failure ever occurs. It is well known within the industry that as drivers are used they actually get FASTER! The fastest a driver will ever be for ball speed are the few balls before eventual failure because of the increased flex happening with the face and the great energy transfer… but where does this flex come from?
OEMs are in the business of distance, and making drivers as long as possible. Thanks to advanced manufacturing, processes, and materials, they can now make drivers right to the limit and truly push the envelope with every single head. TaylorMade, for example, even openly talks about how thanks to the new speed injection on the M5 and M6 drivers, they are building drivers beyond the limit and dialing them back—pretty cool technology if you ask me.
Fast drivers + high swing speed players = a perfect storm for drivers to become hot.
The CT (characteristic time ) limit is .239 with an allowance of .018, meaning the absolute limit the OEMs have to work with is .257. If you get a driver that was measured by both the factory and your tour department and deemed legal at say .255 then you are good to go. But, without daily testing, we dont’t know when this “hot” stage in the driver’s life occurs: 100 balls? 1,000? What if you test before and after a round and it only fails after? No way to tell when it failed, maybe it was after the final tee shot and it was never non-conforming during play, what is the outcome? It’s not like the .003 increase would offer any distinct advantage once you factor in player and environmental factors, but still under the rules it’s a NO-NO.
You could even go the other way when it comes to wedges. I’ve been suggested the hypothesis that you could mill illegal grooves into a wedge beyond the limit but after a single bunker practice session of say 150-200 shots it’s now legal and RIGHT at the limit because of wear. In reality, this CT limit-pushing greatly benefits the regular golfer and allows any players to get the absolute most out of their driver (legally) when they get fit for a new one. Tour players get this same advantage, but because of their swing speeds, the likelihood of then getting to the fastest/hottest point is going to happen, well…faster.
Obviously lots of discussion about fast (hot ????) drivers so let’s talk about that for a minute.
As they get used, a driver will get faster. The “hottest” a driver will be is right before the face fails!
To think this is a new thing is shortsighted, there are other examples…

Tolerance, Tolerance, Tolerance…
With so much talk about the tolerances of each head, what about the CT measuring devices? We’re talking about .003 microseconds! One tiny change to the way the test is conducted by the user, or how the machine is calibrated and there will be variance.
It’s the same thing when talking about lies and lofts, if unknown to you, the machine you use is off by a single degree then at least the whole set is “off” which from a players perspective is fine as long as you are seeing the intended results. Unfortunately, when it comes to the rules this could be the difference between a driver passing and failing—that’s a big deal.
What this has exposed and shown the world is that modern drivers really are pushing the limit for all golfers. Does it mean we need a rule roll back or adjustment to the CT variance to get the “hot” driver okayed…OR, does this mean the governing bodies to need put a real clamp down of how and when a driver can be tested and what it really means to “be at the limit”?
There is certainly a lot to discuss on many sides of this issue from player, rules, technology perspectives, but if one thing is for sure, this really is just the tip of the iceberg to another element of the distance debate.
