MOI (Moments of Inertia)

MOI is a measurement of resistance by a force, to a surface plane that causes rotation deflection when the force is moved away from the center or sweet spot. MOI formulas, and there are a few, takes design elements such as mass and CG into account, when calculating MOI. The higher the measured number, the higher the MOI.

The measurements for MOI came into vogue a few years ago when golf club designers found that moving the weight to the heel and toe and perimeter of the club produced less twisting if the ball was not struck on the sweet spot. Basically higher MOI enlarged the sweet spot, giving better results for golfers with inconsistent ball striking on the putter face.

Putters that are face-balanced, center-shafted, and have high heel and toe weighting, normally rate higher for MOI.

As always, there can be exceptions. For example, our M-PULSE MALLET has very good MOI numbers, however, the mass down-the-line weighting also has great CG numbers that affects the MOI rating numbers. Our Mallet design has the best of both worlds.

CG (Center of Gravity)
The CG can be a simple measurement or a complex measurement, based on the object's mass weight and the placement of that weight. For instance, a solid square of one type of material will have CG in the center of the shape. If you add weight to one side and keep the same shape, the center of gravity will move to that side.

When measuring complex shapes with various materials, i.e., on a golf club, finding the CG will require complex formulas to pinpoint the CG.

CG can influence balance, feel, launch, etc. In a club design, weight can be moved around the design to accomplish CG placement as well as verious features including MOI, Face Balance, Shaft Balance, etc.

SWING WEIGHT:
The swing weight is a numeric measurement done on a balance scale designed to measure the swing weight and total weight of golf clubs. It is a starting point for making sure the clubs have a matched weight within the set, or to make swing-weight adjustments to a club(s).

Swing weight in putters is a personal preference for the golfer. In the past few years, the head weight of putters has increased, and so has the swing weight. For most golfers, a swing weight of C-8 to D-8 is acceptable.

A putter measuring in the 33-36 inch length range, with the head weight in the 330 gms. to 360 gms. range, is very typical to meet a swing weight in the above range.

As the length of the putter is increased, the swing weight also increases with a given head weight. As a rule of thumb, in order to keep most putters in an acceptable swing weight range, short putters should have a heavier head weight, and longer putters a lighter head weight.

For belly and long putters, the preference has been for a heavier head weight to help compensate for the heavier shaft and grip.

In our custom-fitting sessions, we have had every conceivable length, head weight, and swing weight that does not fit the model. I highly recommend a custom-fitting session to get the putter "dialed in". In a custom-fitting session the putter can be fine-tuned, but the golfer must communicate what he likes, what feels best, and what produces consistent results.

DEFINITIONS--IMPORTANCE TO PUTTING (CONT.)

PUTTER LENGTH:
The Length of a putter is a measurement from the butt end of the grip, down the shaft to the bottom of the sole.
The length of a custom-fit putter should only be measured after the precise lie angle is found, and after the golfer's physical stature, putting posture, etc. are determined. The correct length will be determined from the fitting session.

Finding the proper length is not complicated. Of the three measurements: Lie angle, Loft, and Length -- the first two are critical. Length has more room for proper fitting. If your grip is down in the palm of the hand, or inches above the wrist crease line, you have a putter length that is not correct.

There should be 1/4" to 3/8" of grip butt end above the wrist crease line of the golfer's top hand placement. Most custom-fitted putters will be of non-standard lengths. As an example, if we measure the length to the wrist line at 34-1/4", we cut the length at 34-1/2" to 34.625. Proper length results in more consistent putting.

NOTE: Off-the-shelf putters come in standard lengths, typically in one inch increments, i.e., 33', 34", 35", etc.

SWEET SPOT:
A spot on the putter face where the putter will not rotate/twist when struck by the ball. Theoretically, the spot is located at the alignment line, dot, or mark.

Finding the Sweet Spot is easy. With the thumb and forefinger, loosely grip the putter shaft near the grip, and let the putter hang down. With a ball in the other hand, strike the putter face in various spots along the face until there is no rotation/twisting at impact. This is the Sweet Spot area and should be the impact target spot for ball contact.

The Sweet Spot can change when the lie angle changes. On a standard off-the-shelf putter with a standard lie angle, the sweet spot should be at the alignment mark. The sweet spot will move toward the heel with flatter lie angles, and toward the toe on more upright lie angles. The CG and MOI will also change.

FACE-BALANCED:
The putter is face-balanced when the shaft angle dissects directly through the center of the face, and the head weight is equal from heel to toe.

In theory, with a face-balanced putter, the putter head feels more balanced, and the stroke release will square up the face at impact. This feature is most beneficial when the golfer has a consistent lie angle, consistent setup ritual, and a consistent putting stroke.

In most face-balanced, fixed lie-angle putters, altering the lie angle changes face balance, and the advantages of a face-balanced putter are lost. REF: Lie Angles

NOTE: The Ontic M-Pulse Mallet is face-balanced through all the lie angle adjustments, from flat to upright, and is very consistent.

ONTIC GOLF: ABSOLUTE CUSTOM-FIT PUTTERS

I will be submitting "definitions" that are used by Ontic Golf to help golfers "know" their equipment. Visit my blog as often as you like to keep informed!

LIE ANGLE:
A measurement of the shaft angle relative to a flat surface plane on which the putter sits. This measurement is normally made on a lie angle gauge designed especially for this purpose.

Most putters "off the shelf" will have a fixed lie angle around 71 degrees and will have a convex (rounded) sole design. The 71 degree lie angle is too upright for 90% of golfers.

Putters with a convex (rounded) sole can be lie angle adjusted, however, the lie angle can change when the golfer rocks the putter to make the lie angle fit their set-up. In most cases the golfer will have the putter toe up. With a convex sole it is very easy to change the hand position and set-up position, which changes the lie angle.

Example: When the lie angle moves flatter, the toe of the putter moves higher. This shifts the CG toward the heel, and the MOI shifts to the toe. These small changes can have a big impact on alignment, absolute loft, ball position, and swing plane.
Results: Inconsistent putting performance.

CUSTOM FITTING the golfer's PRECISE LIE ANGLE is the MOST IMPORTANT PROCESS in the putter-fitting session. However, the precise lie angle comes from a total fitting session with the golfer. Posture, eye, and ball position are also taken into account when fitting a putter.

We have found from our fitting sessions that 95% of all the golfers we fit will have a lie angle below 70 degrees. The largest percentage will be around 66-68 degrees. Just one-half of one degree can make a tremendous difference in putting performance.

Only Ontic Golf putters, with our patented Dynamic Sole Technology (DST) and our patented Lie Angle Adjustment Feature can and does guarantee dialed-in lie, length, and loft for precise, consistent set-up. Correct lie angle is critical, and it is the foundation for making more putts, time after time!

Next Time: Putter Length and the Sweet Spot! Don't miss it.

THE IMPORTANCE OF CUSTOM FITTING THE PUTTER

Golf is really two games in one. One is airborne (tee to green); the other (putting) is keep it on the ground. Both are important skills if you wish to accomplish the object of the game -- getting the ball from tee to green and in the hole in the least number of shots against the par value for the course. Both skills require controlling the ball with accuracy, speed, and distance.

Putting is the one skill that is credited for lowering scores. Sadly, the putter is the one club that most golfers purchase without much thought. They purchase the latest fad just because a Tour Pro used it, even though he was paid to do so. Or they purchase a putter just because it has a prestigous name and is expensive. These putters are almost never custom fitted to the golfer! Experience shows that 95% of the putters "off the shelf" never have the correct lie or length.

Having a custom-fit putter will immediately improve a golfer's putting performance. But what area of fitting should the golfer be most concerned with? Answer: fitting the lie angle. No other fitting procedure should be done until this is done first. Fitting for lie angle should be done in conjunction with proper set-up posture for eye and ball position, physical build, etc.

Let me be clear!! Custom fitting the putter is the most important process for the most important club in your bag to lower your scores. Having the correct lie angle is the foundation for all other putter fittings. Without the absolute correct lie angle, all other fittings and rituals will not and can not be consistent.

WORD OF CAUTION! Because most putters have a convex sole, they can not be adjusted for lie angle that is consistent putt after putt. There is only one putter design that guarantees consistent lie angles because of their patented sole design -- Ontic Golf Putters!

For most golfers putting is the least-practiced skill. I am sure you have heard that "practice makes perfect"....Practice does not make perfect...Perfect practice makes perfect. You cannot practice with a bad club and/or a bad putting ritual and hope for better results.

I trust this information wakes up that great putter in you. If you are serious about lowering your score, the best way is through making more putts...with a properly custom-fit putter; I guarantee it.

I look forward to hearing from you; your questions are greatly appreciated.

WHY DON'T YOU HAVE A CUSTOM-FIT PUTTER (CONT.)

Let's get into what is needed for a PURE-FIT custom putter. If you really want to be a better golfer, then having the right equipment, and especially having a custom-made putter, is a major step. Keep in mind -- equipment fitting is not an exact science. There are too many variables in hand size, body types, swing mechanics, set-up postures, etc., to be 100% fitted.
PUTTER LENGTH:
Most putters on the market offer lengths in 1-inch increments. I recommend that the putter be no more than 1/4-3/8" longer than fitted. Having the correct length is vital for the correct set-up posture, eye position, ball position in your set-up, arm angle, and hand position on the grip, distance you will stand from the ball, and swing plane! (Whew!)
At the end of this article there will be a web page that will show you the correct method to measure for your putter shaft length. It would take another article to describe the details for custom-fit lengths.
PUTTER LOFT:
All putters have a loft that has been designed and specified by the manufacturer. Having the correct putter loft is a matter of interpretation. There has been a trend recently to have less loft on putters. The major reason for this is better roll on the type of grasses and mowed height on today's greens.
Putter loft, and more importantly, the effective putter loft at impact to the ball, greatly affects the roll characteristics of the ball. The effective loft or actual loft are controlled by many factors before and during the stroke. Ball position in the stance, hand and shaft angle in the set-up, hand and shaft angle at impact, and angle of putter head at impact, control the effective loft of the putter. Based on test data Ontic Golf has conducted, the best roll characteristcs fall between 2-3 degrees of loft.
Golfers are not machines, so there is a lot of variation in the individual putting stroke. However, in order to take advantage of the actual loft of the putter, the ball position should be no more than 1/4" forward of the bottom of the swing arc. The putter should be traveling parallel slightly before and after impact. If the putter is traveling parallel, the putter face will contact the ball just below the equator.
The ball is a sphere: 1.684 inches in diameter. It is approximately 90%-95% dimples. The actual outside surface area is very small, so the putter face contact area is very small -- and can vary from putt to putt.

The correct Loft, Lie, and Length of your putter insures that it sits flat on the putting surface and will make you a winner on the greens. Let's face it, putting and the putter is the most important club in your hands! MAKE SURE IT FITS!

GOOD PUTTING IS DOING THINGS RIGHT; GREAT PUTTING IS DOING THINGS RIGHT EVERY TIME!

Remember, If you want to be a better putter and lower your scores, you need to have a better custom-fit putter! THE TOUR PROS DO!

THE PUTTER -- THE MOST IMPORTANT CLUB IN YOUR HANDS

WHY DON'T YOU HAVE A CUSTOM-FIT PUTTER?
Let Length, Lie, and Loft lift your putting to a new Level!
Let's face it; a 300-yard drive and arching shots to the green are fun to hit and fun to watch. Drives that are 10-15 yds. offline can still provide a "reasonable" shot, however, missing a putt by a fraction of an inch will cost you a stroke and maybe the tournament. Kenny Perry stated in a recent article, "If I could make just 3 more putts per tournament, it could mean the difference between winning or finishing in the top 10."
He did not say 3 more drives in the fairway or 3 more shots on the green -- he said 3 more putts.

The Putter is the most important club in your hands. Putting is the most important part of your game to dramatically lower your score.

Golf is really two different games: the power, distance ,and accuracy game to hit greens in regulation and get the ball into the air and close to the target. (Stats. show Greens in Regulation for Tour Players average 70%, or 13 holes in 18).

The other game is the putting game: Control of the putter in order to make contact with the ball with just the right amount of force to get the ball to the hole. It is the control of speed, speed, speed. It is stroking the ball to keep the ball down on the grass. It is reading the putting surface for contour, uphill, downhill, side hill, and a combination of all of these to determine how other elements affect the putt.

Did you know that on a regulation Par 72 Course, 50% of your strokes are on the green.

Did you know that the Tour Player with the best putting percentage in 2006 was also 170th on the money list?

Golfing -- Can Help You Live Longer!

In case you did not read an article in a current Sunday paper, by Michael O'Shea, I would like to encourage you with some of the reasons this article gives to hit the links!

1. Married couples who play a round of golf on a regular basis can add 5 years to their life.
2. For maximum benefit on the course, GET OUT AND WALK THE COURSE. Start out by walking every other hole until you're walking the entire course. A recent study shows that golfers who walk 36 holes a week burn around 2,900 calories, which could lead to a 40 lb. weight loss in just 1 year.
3. Walking the course will improve your game -- Just think about it. You will be able to SEE THE DETAILS OF THE COURSE, leading to BETTER CLUB SELECTION and BETTER SHOTS.
4. Walking will improve fitness and improve overall health.
5. The social "togetherness" will improve your mood.
6. Because golf can be played at any age, it's THE SPORT THAT KEEPS ON GIVING!

I hope these suggestions will help you to not only improve your golf score, but also improve your personal relationships!

Get out there and Walk! Enjoy the Game!

The Art of Putting: The “Other” Game of Golf (Post 2)

What is more important than putting? …..Absolutely Nothing!
Putting is the single most important skill that can level the playing field and lower your score. It is the part of the game that wins tournaments, or wins local matches.

Making putts will bring a solid CONFIDENCE FACTOR that flows to other parts of your game. Never step up to a putt with the thought that you will not make a good stroke or make the putt. NEVER!

Don’t get me wrong; I love to hit the driver and great approach shots. But none of that matters if you can’t get the ball in the hole with the fewest strokes! With that said, I want to help you become better golfers by making putting the main focus for lower scores.

So, with your new $400 driver, custom-fit irons, and the latest “exotic bird”, “spider”, or painted billboard, off-the-shelf putter, you head to the course to shoot that low round.

But the most important club in the bag for lower scores – the putter -- is not custom fit for you. It is probably too long, and the lie angle is way too upright. What are you thinking?

The three important design features for improving putting are: An absolute custom lie angle, the correct length, and the correct face loft. Of the three, I guarantee that having the correct custom lie angle is the most important feature to become a consistent putter.

FYI – Putters off the shelf are 70-72 degrees upright. 90% of the golfers I fit fall between 66-69 degrees.

Stay tuned to my next blog.

Welcome to Bernie's Blog

THE ART OF PUTTING: THE "OTHER " GAME OF GOLF

These blogs are meant to bring a new and fresh dialogue to the Art of Putting. It will be a series of concepts, thoughts and experiences that I hope I will help you to improve the most important skill needed to quickly improve scores: Putting.

We will discuss many areas of putting that have been, and continue to be taught, that are complete myths.

There are two games skills in golf: The long ball and the iron , and the chipping game. But ask all of the pros, and they will tell you that putting wins tournaments.

"But Bernie, I can putt with my eyes closed and the ball behind my back. I am not going to change! " Great! Why change what works for you? However, we can all learn something to take just one more stroke off our game...are you interested?

Stay tuned in. Vision is beyond seeing.
