Some fitters actually attempt to approximately MOI match a set of clubs by “progressive swingweighting” – increasing the club swingweight by typically 1/2 swingweight point between clubs – for example, the 6 iron swingweight would be 1/2 point higher than the 5 iron swingweight.
What is Moi matching in golf?
What is MOI Matching? The MOI of any object is a measurement of its resistance to being put in motion around a defined axis of rotation. Golf clubs are swung in motion about the axis of either the spine or the unhinging of the wrist-cock angle when the club is released to hit the ball.
What is the Moi speed match hardware?
The older MOI Matching system required clubmakers to manually measure 4 different specifications of each club and then use the accompanying software to calculate the MOI of each club. Thus, the MOI Speed Match hardware is much faster to use to quickly measure the MOI of any club.
Does swingweight match Moi matching?
Back in the 1920s when swingweight was developed, its originators were aware of the principles of MOI matching and tried to make swingweight matching of clubs simulate MOI Matching. They failed because the principle of the swingweight scale they developed could not truly accomplish the task of measuring the MOI of a golf club.
How are golf clubs measured for Moi?
The “favorite club” can be measured for its MOI using the TWGT MOI Speed Match machine, after which the other clubs are then built to match the MOI of that “favorite club (s)”. The most common method used by clubmakers is to build test clubs based on their fitting recommendations made for the golfer after going through the entire fitting process.
What is MOI matching in golf clubs?
MOI Matching is simply a replacement for swingweight matching in the fitting process. Clubmakers will fit golfers for every one of the other key fitting specifications based on the same fitting procedures that they have developed and with which they are experienced.
Can you mix and match golf clubs?
As a whole it is not only ok to have a mix of golf brands in your golf set but if done consciously it will ensure you have the best set of clubs for your swing.
Does your driver have to match your irons?
There is no requirement to match your driver with your woods. Brand, club head, shaft, weight and length are all parts which can match but golfers are best focusing on the combinations which deliver the best results for each club individually.
How do you measure Moi on a golf club?

And today'sMoreThe higher the moi. The less the club is going to twist in any sort of off-center hit. And today's clubs are engineered for that in a variety of ways primarily they've got weight on the outsides.
Can I mix and match golf irons?
As consumers and golfers, we're free to pick and choose whatever clubs we want to round out a 14-club set. We can mix and match brands, models, types — there's no rule stating what kind of clubs we have to play. This means you're not only free to choose, but you also have to choose.
Should all my golf clubs have the same shaft?
Clubfitters recommend golfers have the same shafts in their wedges and irons. Different shaft flexes & weights can lead to loss of distance, greater shot dispersion and different ball flight than expected. Better players can however select softer flex shafts for high lofted wedges for more control.
Should my 3 wood shaft be the same as my driver?
Your fairway wood shafts should be slightly (5 to 15 grams) heavier than your driver shaft. So if you are playing a 65 gram driver shaft (noted by a numeral 6. 65, or some other designation on the shaft decal), your fairway woods should be 70 to 80 grams.
Should my driver swing be the same as my iron swing?
The main difference in a driver swing vs an iron swing is the way you attack the golf ball. Iron swings must drive down into the ball so that the loft of the club does the work to get the ball off the ground.
Why do I hit my driver well but not my irons?
There is a myriad of reasons why you hit your driver better than your irons. However, the root cause for most golfers stems from posture, the position of the ball in your stance, and your swing plane. Plus, the optimal ball speed and forgiveness produced by a driver make it easy to launch.
How is Moi measured?
MOI is measured in grams per centimeter squared and shows how much resistance a clubhead has to twisting. The more resistance it has, the higher the MOI reading and, importantly for golfers, the more forgiving the club will play.
What does high MOI mean?
On off-centre hits the club head is forced to rotate away from the target resulting in a loss of directional control and ball speed. A high MOI means that the club is more stable and therefore more resistant to twisting, which translates to more ball speed and a straighter shot.
Should all my golf clubs be the same swing weight?
All of Your Clubs Should Have the Same Swing Weight Even if you think your clubs are a bit light or heavy for you, all the clubs in your bag should at least be very close to the same swing weight. Using clubs with different swing weights typically leads to poor performance on the course.
Can a driving iron go as far as a driver?
If accuracy is more of a concern for you, then you should probably think about the driving iron. It is a bit easier to hit the driving iron straight than it is the driver. You can expect to get a good 20 to 30 fewer yards from a driving iron than you will from a driver.
Can high handicappers use driving irons?
If you are hitting the 3 Iron the best, you should consider a driving iron as a high handicapper. Select the driving iron that meets your swing and ability that will inspire confidence when you stand on the tee and require a low penetrating shot with accuracy in mind over distance.
Are driving irons more accurate?
Driving irons will fly higher than a long iron but they will be lower than hybrids, this is important. Driving irons are also a little more accurate than a hybrid. Although hybrids will land more softly so can be better for long approach shots.
When should you not use a driver in golf?
You should always hit driver, except in these 4 situationsThere's a forced carry. ... The fairway squeezes. ... Driver leaves an awkward shot. ... Your opponent is out of bounds.
How to find the right MOI for a golf club?
The “favorite club†is measured for its MOI using the TWGT MOI Matching System, after which the other clubs are then built to match the MOI of that “favorite club (s)â€.
What is MOI in golf?
The MOI of any object is a measurement of its resistance to being put in motion around a defined axis of rotation. Related to golf clubs, if each club in a set requires a different amount of force to swing the club (swinging the club to rotate around our body), the golfer cannot be as consistent swinging each different club in the set. In most simple form, MOI matching scientifically makes each club require the same amount of effort to swing. This is what makes MOI matched clubs offer better shotmaking consistency than swingweight matched clubs. Swingweight matching does not make each club the same in terms of the amount of force required by the golfer to swing each club and hit the shot. MOI matching does. However, because golfers can be quite different in their strength, tempo and swing mechanics, the right MOI must be identified and custom fit for each golfer to allow the concept to properly work.
How much does the swingweight increase with a MOI matched club?
Most typical is to see the swingweight increase by 0.5 swingweight points per club down through the set. This is very definitely one of the main reasons golfers like the swing feel of their MOI Matched clubs and do experience an improvement in shot consistency.
Why did swingweight match fail?
They failed because the principle of the swingweight scale they developed could not truly accomplish the task of measuring the MOI of a golf club. Over the decades since the development of swingweight, engineers familiar with the principles of MOI have been in agreement that MOI matching would truly make all clubs within a set swing with exactly the same feel, while swingweight matching could not.
What is MOI match?
In 2006, TWGT introduced an upgrade to the original MOI Matching system with the MOI Speed Match System. This system consists of an electronic device that directly measures the MOI of any golf club in one operation. The older MOI Matching system required clubmakers to manually measure 4 different specifications of each club and then use the accompanying software to calculate the MOI of each club. Thus, the MOI Speed Match hardware is much faster to use to quickly measure the MOI of any club.
What is a favorite club?
A “favorite club†may be defined as a club with which the golfer is most consistent over all others, and which the golfer has the utmost confidence in their ability to hit the ball solid and on-center more often than the other clubs in the set. After research and testing, TWGT believes that a one reason golfers have “favorite clubs†is that the MOI of those clubs happens to match the strength, tempo and swing mechanics of the golfer noticeably better than the MOI of other clubs.
Can you match all woods to one MOI?
No. TWGT testing and feedback from many of the clubmakers using MOI matching in their work has proven that because woods and irons are so different in their length ranges, better results are obtained by matching all the woods to one MOI, and then matching all of the irons to another MOI, with both chosen specifically for each golfer either on the basis of the “favorite club†or the “test club†approach. The difference in MOI measurement between the woods and irons typically is for the woods to be 50 g/cm2 higher in MOI than the irons.
How to find the right MOI for a golf club?
The “favorite club” is measured for its MOI using the TWGT MOI Matching System , after which the other clubs are then built to match the MOI of that “favorite club (s)”.
What will a golfer notice when switching from swingweighted to MOI matched clubs?
We have yet to hear from a golfer for whom MOI matching was performed did not notice a difference in the swing feel of all of the clubs in the set, and a minor to significant increase in the percentage of solid, on-center hits with their clubs. If the golfer “waggles” each MOI matched club (providing they are sensitive to the weight feel of each club) they will detect a progressively increasing headweight feel as the clubs get shorter in the set. But as soon as the clubs are swung full, the golfers all report that they can close their eyes, switch clubs in the set, and not really detect any difference in the total swing feel of the clubs from each other.
What is MOI Matching?
The MOI of any object is a measurement of its resistance to being put in motion around a defined axis of rotation.

In most simple form, MOI matching scientifically makes each club require the same amount of effort to swing. This is what makes MOI matched clubs offer better shotmaking consistency than swing-weight matched clubs. Swing-weight matching does not make each club the same in terms of the amount of force required by the golfer to swing each club and hit the shot. MOI matching does. However, because golfers can be quite different in their strength, tempo and swing mechanics, the right MOI must be identified and custom fit for each golfer to allow the concept to properly work.
Has MOI Matching ever been done previously in golf clubs?
Yes, there were two previous times in golf equipment history in which companies attempted to offer MOI matched golf clubs. In the 1970s, a company named Sounder Golf offered sets of woods and irons which claimed to be matched by weighting the clubs at specific points within the shaft. The Sounder clubs never caught on for two reasons: 1) Sounder was under-capitalized and unable to generate enough demand through their marketing programs. 2) Every set of Sounder clubs was built to only one specific MOI. Because golfers are different in strength, tempo and swing mechanics, one MOI measurement could never fit the MOI requirements of each golfer.
Does MOI Matching change the fitting process for the golfer?
No. MOI Matching is simply a replacement for swingweight matching in the fitting process. Spargo Golf will fit golfers for every one of the other key fitting specifications based on the same fitting procedures that we have developed. Once all of the fitting specifications are determined by the clubfitter, then MOI Matching is brought in to guide the clubmaker in how the clubs will be assembled with regard to final headweight, and in some cases, the final length adjustments.
Is there any aspect of the fitting or performance of the shafts that is changed by MOI Matching?
Very rarely, if ever. As we said, the selection of the shaft is made on the basis of the same fitting procedures the clubfitter is comfortable with using to identify the best shaft for the golfer’s swing speed and swing characteristics of the downswing transition, downswing tempo/acceleration and wrist-cock release.
Will the woods and irons all be built to have the same single MOI?
No. TWGT testing and feedback from many clubmakers using MOI matching in their work has proven that because woods and irons are so different in their length ranges, better results are obtained by matching all the woods to one MOI, and then matching all of the irons to another MOI, with both chosen specifically for each golfer either on the basis of the “favorite club” or the “test club” approach. The difference in MOI measurement between the woods and irons typically is for the woods to be 50 g/cm2 higher in MOI than the irons.
How many points are the irons on a ping?
After I got the irons from PING, I ran them all on my MOI Auditor and they're all within about 6 points ... more than accurate enough for my purposes.
What is the difference between 7 gram and 8 gram irons?
The 7 gram difference is the difference used to set iron sets up for a swingweight matched set for 1/2" increments... in a perfect world. And to set up for putting irons on a frequency slope. In reality, it's a bit less for long irons, 7 grams for mid irons, and short irons it moves up to 8 grams (ish). That's with everything else like shaft weights, grip weights, etc spot on which rarely happens unless you have the ability to hand-pick through a larger amount of shafts.
How much swingweight difference per iron?
toyed with. Have always set up irons straight swingweights. Plan on a 2/3 swingweight difference per
Do you hit the ball from the same place in your stance with MOI irons?
The main thing to realise is that you need to hit the ball from the same place in your stance with MOI irons.
Do you do more weight on a MOI scale?
For MOI, you are doing a little more weight, as the swingweight will progressively increase as the irons get shorter as opposed to reading the same on a scale.
How do swingweight matched clubs differ from MOI matched clubs?
How do swingweight matched clubs differ from MOI matched clubs? If you have a set of MOI matched clubs, you will find that the swingweights of the higher irons are lower than the swingweights of the shorter irons . Some fitters actually attempt to approximately MOI match a set of clubs by “progressive swingweighting” – increasing the club swingweight by typically 1/2 swingweight point between clubs – for example, the 6 iron swingweight would be 1/2 point higher than the 5 iron swingweight.
What is MOI in golf?
MOI – this is an actual physical measurement that is made for a golf club, it has dimensional units of mass/ (length*length). It is a measure of how easy or difficult it is to swing a golf club. Interestingly, the weight of the grip has little if any influence on the measured MOI of a golf club.
What is MOI matching?
They also believe that if you have a set of MOI matched clubs, that you can ask a player to swing their 5 iron and 9 iron with their eyes closed and they will not be able to tell you which one they are swinging.
What is swingweight in golf?
SWINGWEIGHT – I believe the concept of swingweight has been best defined by Ralph Maltby of Golfworks – “the measurement of a golf club’ s weight about a fulcrum point which is established at a specified distance from the grip end of the club.” Swingweight is all about the weight distribution between the head of the golf club and the grip end of the golf club. Increasing the head weight and increasing shaft weight make swingweight increase, increasing the weight of the golf grip makes swingweight decrease. A relative weight scale was developed to denote different swingweights – so a D1 swingweight is larger than a C6 swingweight.
What would a good club fitter know?
A good club fitter would know more about not only how much weight to add but where (and how) to add it.
How many points should the swingweight go down?
The swingweight should go down by 1.3-1.4 points for every inch the club's overall length increases . That's about one and a third points per inch. This is a little more precise about the slope.
Is my swing a WIP?
Yes, my swing is also WIP. Hcp is about 15, and there is still a huge amount of work on my swing to be done.
