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 Gear Dive WITB Edition: Adam Scott
In this WITB edition of The Gear Dive, Johnny chats with JJ VanWezenbeeck and Aaron Dill of Titleist Golf on the ins and outs of Genesis Invitational Champion Adam Scott’s setup.
Adam Scott WITB details below
Driver: Titleist TS4 (10.5 degrees, A1 SureFit setting, 2-gram weight)
Shaft: Mitsubishi Kuro Kage XTS 80 X
- Scott put the Kuro Kage in play this week. Per Titleist’s J.J. VanWezenbeeck, “Adam Scott switched to the TS4 driver at the ZoZo Championship due to head size, shape, and improved launch to spin ratios. This week, after discussions with Adam, he went to a shaft he had previously played for increased stability. He felt the shaft went a little far and he lost head feel. We went on course with lead tape to get the feels to match up then weighted the head to preferred swing weight after testing.”
3-wood: Titleist TS2 (16.5 degrees, A1 SureFit setting)
Shaft: Fujikura Rombax P95 X
Irons: Titleist 716 T-MB (3-iron), Titleist 680 (4-9 irons)
Shafts: KBS Tour 130 X
Wedges: Titleist Vokey Design SM8 (48.08F, 52.08F, 56.10S), Vokey Design SM8 WedgeWorks (60.06K)
Shafts: True Temper Dynamic Gold AMT Tour Issue X100
Putter: Scotty Cameron Xperimental Prototype Rev X11 (long)
Ball: Titleist Pro V1
Grips: Golf Pride Tour Velvet
The Wedge Guy: An examination of proper “release”
One of my favorite ‘contributions’ to this game I love is helping golfers t an “ah-ha” moment, wherein they gain an understanding of the idiosyncrasies of the golf swing that helps them make progress in their ball striking. In so many cases with recreational golfers, keys to improvement can be much more conceptual than physical. In other words, helping a golfer discover what really should be happening in various parts of the golf swing leads them to make their own swing alterations to adopt this new understanding.
I firmly believe that teaching through understanding is much more productive than trying to teach “a new move” through the physical approach. From my observation of recreational golfers, particularly those with “homemade” swings (which all have the potential to produce better and more consistent results in my opinion), one of the most misunderstood intricacies of the golf swing is how the club should be “released” through the impact zone.
Almost universally, golfers seem to think that the club releases through impact by or with an unhinging of the wrists, so that the left arm and shaft form a straight line.
If you genuinely want to improve your ball striking, your distance, your consistency and your scores, I suggest you pursue a genuine and technical understanding of this critical segment of the golf swing. Because most of you are
stuck in front of your TV right now–watching more golf than you are playing–you can make this time count. Every chance you get, watch the slow-motion videos of the golf swing from behind the golfer, looking down the line. A
straight-on view of the golf swing does not reveal this angle, but that is mostly what we are given in swing analysis by television and magazines, unfortunately.
[I’ll offer too, that you can learn a lot more from watching the LPGA players than the guys, as these very talented ladies are much closer to our own strength profiles. In my opinion, most of them are much more fundamentally
sound in their mechanics as they simply have to get the most efficiency out of the swing.]
What you will see, particularly with the wedge and short iron shots is that the hands and arms follow a path through impact that very nearly “covers” their position at address, where a distinct angle is formed by the left arm and shaft of the club…again, looking from behind the golfer down the target line.
As you study these videos and still photos, you’ll see that in the longer, more powerful swings–driver, metals, hybrids–the hands drift a little higher and away from the body more than they do with the middle and short irons, but the angle is still there. As you watch these guys hit the delicate short shots around the greens, the hands almost identically cover their address position.
That’s because a proper “release” of the club is not as much an unhinging of the wrists, but rather a rotation of the hands and arms through impact, in concert with and driven by the rotation of the body core itself. Close examination shows that the hands remain almost directly in front of the sternum through the entire impact zone, and the forearms and hands rotate – not unhinge – so that the club is squared at the ball for consistent impact.
Now, all this diagnosis would not be worth a dime to you if I didn’t show you how to experience this for yourself. Like most new physical activities, you are always best served by trying to LEARN IT IN SLOW MOTION! Simply pick up your 8- or 9-iron and find a place in your house or garage where you won’t take out a table lamp, and make very S-L-O-W swings, while concentrating on making this rotational release motion.
Your goal is to set up at address with the left arm hanging naturally from your shoulder, not pushed out toward the ball. Take the club back with a rotation of the body core, and then back through the impact zone, concentrating on making the left arm and hands exactly “cover” their address position. The angle of the wrists is maintained, and the club rotates through the ball, as your body rotates through impact.
Once you get the feel of it in slow motion, make slightly faster swings, concentrating on the path of the arms and that rotational release. When you actually hit balls with this newly-learned release–DO IT AT 35-50% POWER–you’ll be amazed at the boring trajectories and effortless distance you will get!
Let’s get some feedback on this, guys. How did you do?
