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.
The Wedge Guy: Swing Weight Part 2 – Non-standard lengths
This is the part of the swingweight discussion where I expect to get lots of dialog, so here goes.
The modern trend in clubfitting seems to “fit” many golfers long and upright, which I don’t necessarily agree with, but can sound off on that later. Today, we’re going to talk about this subject, and I’m going to share my theory on what does and should happen to swingweight.
The idea of fitting a golfer with longer shafts is to accommodate his or her height and posture. Let’s say my friend who’s 6’3” really likes my irons, and wants a set “just like them”, but he wants them built to his own specs of 1” overlength. So, to accommodate his larger size and assumed strength, we build him a set of irons just like mine, except that the shafts 1 inch longer than mine are. Now, that one inch in the butt of the golf club shaft only adds about 2 grams to the overall weight of the club, and does nothing to the flex profile. So his new irons are EXACTLY like mine – same shaft flex, same heads, same everything.
BUT, when we put his new irons on the swingweight scale, he goes ballistic, because they read D7-9, rather than the D2 that I play. But they are not heavier than mine: they are just like mine, only altered to accommodate his size.
However, if he insists that they should be only D2, as a clubmaker, I have my work cut out for me. First, I have to grind weight off the clubheads . . . considerable weight, as much as 5-8% of the mass . . . with greatly alters the club, right? And removing that much mass then makes the shafts play much stiffer, increasing the frequency by a half a flex or more. So, in order to “match” the swingweight, I’ve created a tremendously lighter and stiffer club – nothing like the irons I have that he liked so much.
Or I guess I could counter-weight the club significantly, which also is dramatically changing the irons that we wanted to be “just like mine.”
What I have always proposed is that we think in the concept of “swingweight equivalent”. If the club is D2 at standard length, it’s going to be D4-5 at 1/2” over, maybe D8-9 at 1” over. When we are making shaft length adjustments that are shorter, that exact same club will be C9 or so at 1/2” shorter than standard.
I really think it’s just that simple. What about all of you?
TG2: Testing Odyssey’s Triple Track 7S putter and BGT Stability putter shafts
I got Odyssey’s new Triple Track 7S putter out on the course to play for a couple of rounds and that Triple Track alignment system is really good. BGT (Breakthrough Golf Technology) Stability putter shafts are a big upgrade over stock steel putter shafts. I review both the Stability and Stability Tour versions. Finally, WITB for the big golf trip this weekend!

Ways to Win: Redemption for Morikawa
Justin Thomas Collin Morikawa stole the show
I had already written the opening paragraph in my head on how solid Justin Thomas is with three holes left in the Workday Charity Open. Three up with three to play. It was over…until it wasn’t. I began rewriting the same paragraph when Thomas knocked in a 50-foot putt on the first playoff hole. That clutch putt gained over 1.14 strokes on the typical tour player from that distance…but then Morikawa rolled in his own improbable 24-footer.
I hesitated to pick up the pen again when Thomas had just over 10 feet on the second playoff hole. Morikawa simply would not go away, and, in the end, he survived the three-hole playoff to walk away with the victory. In retrospect, he was certainly a deserving champion. Other than a nervy third round disappointment, Morikawa was solid all week. It was his time.
Comparing any player to Tiger Woods is a somewhat ridiculous exercise. However, the way Morikawa gets it done and his consistency has hints of Tiger. For starters, his streak of 22 consecutive cuts made to start a PGA Tour career is second only to Tiger Woods. At this point in his career, Morikawa has won more events than he has missed cuts. There aren’t many pros that can say the same.
Morikawa’s consistency and brilliance largely come from his ability to separate from the field with ball striking and, specifically, his iron game. Tiger Woods made reliable ball-striking a staple throughout his career. Looking at Morikawa’s performance over the four-round tournament, it is obvious that approach is the most dangerous weapon in his bag. He gained 3.6 strokes on Thursday and more than six strokes on the field Sunday. His approach game kept him in the tournament despite losing strokes with the flatstick.
Morikawa is ridiculously good with his irons. Utilizing the shot distribution chart in V1 Game, we can see he rarely misses the green from close range, and he hits it, on average, inside 25 feet from every distance bucket except from 150-175 yards. In fact, 150-175 yards looks like somewhat of an anomaly for Morikawa. His proximity on average is “only” 32 feet from this distance. In fact, for all buckets over 100 yards, it is the only distance bucket in which Morikawa loses strokes to the field. Again, using V1 Game’s approach analysis we can clearly see the Proximity Trends and Strokes Gained information by bucket. Morikawa gains between a 0.1 and 0.3 strokes with his irons every time he hits a shot. That is a tremendous asset to separate from the field. He simply has more birdie putts from closer distance than the vast majority of the field.
Still Have to Close
Morikawa’s approach game aside, he still has to close. A few weeks ago he was unable to convert from short distance to extend a playoff. In a way, this week was a redemption. Morikawa putted beautifully for the majority of the week, gaining more than three strokes with the flatstick. That does not even include the clutch 24-footer he made in the playoff to extend the match.
However, there is still significant room to improve on the greens for Morikawa. Looking at his putting performance for the week, he did lose strokes from 10-20 feet with one three-putt and very few makes in that distance. Morikawa will need to improve with the putter to continue to convert his ball striking into trophies. However, his consistent iron game should continue to give him plenty of opportunities.
Much can be learned from seeing how the pros manage the course and get it done from day-to-day with different parts of their game. The big takeaway this week: hit it closer and you’ll make more putts. Hitting the green more often takes stress off of one’s putting and short game.
