Does Your Weight Conform?
Hi Frank,
I really enjoy your column and read it every week. I purchased two XYZ drivers with different shafts and lofts. These drivers come with four adjustable weights, two 2 gram and two 10 gram. After tinkering with the weights in each driver, I decided to try one driver with all 10 gram weights (two from each club). It is a little heavier but I have picked up about 20 yards of distance(from 230 to 250). Is my driver still conforming with four 10 grams weights instead of the two it was shipped with? Have I increased my driving distance because of the added mass?
Randy, MN

First, thank you for your kind comments.
I have excluded the brand name of your driver in your question to discourage our readers from promoting special favorite products and in your case, the brand is irrelevant as the question has little to do with the type of driver but rather how you have weighted it.
By placing four 10 gram weights in the weight ports of your driver -- supplied with only two 10 gram weights and two 2 gram weights -- is not a violation of the rules. There is no restriction on the weight of a driver head. I dont know how the USGA will react to increasing the weight of a driver which may at the same time increase the MOI of one which is at the maximum limit by design. Increasing the overall and peripheral weight of a driver head will increase its Moment of Inertia and may place it over the limit. I dont think this is going to be the case with your driver but I dont believe the USGA, when placing a limit on the MOI thought about this eventuality.
Having said this, the additional 16 grams in head weight will project the ball a little faster, but only if you have the same head speed. The same head speed is highly unlikely as it requires an increase in energy on your part. Even if you had the same head speed this increase in head weight will contribute very little to the distance and certainly no where near the magic 20 yard increase you are experiencing.
As an aside; it is amazing how most new products feature something, which will give us more distance and the implication is, 20 yards. Golfers also come off the course claiming that the new club ' as long as it behaved itself -- or ball, has given them 20 more yards. One infrequently hears, This new drive has increased my distance by 7 or 13 yards. The increment is always 20 yards.
In your case Randy you have actual measurements, which I am sure you have checked. The only way one driver of identical make and model will give you increased distance of 20 yards is be because you have, through the relocation of weight, changed the c.g. (center of gravity) of the head and thus the face presentation to the ball and thus been able to launch the ball more efficiently. This would mean that your launch conditions were so far off to begin with that you should probably not have selected this driver in the first place.
So, bottom line is that you may be able to gain 20 yards only by launching the ball more efficiently assuming you were way off to begin with but this has nothing to do with -- or very little -- the increase in weight.
Randy, the Magic is in you not the club.
Good luck
Going for Gold
I've finished 'Just Hit It' and '...may the church say amen!' I could bore you with all the things I've learned from your insight (both from your newsletter and book) but I'll narrow it down to the most important; I've moved up to the gold tees and this game is fun again!
But there is a problem; this has now put more pressure on my putting. You see, now I'm on more greens 'in regulation' and have something I rarely had to deal with 'from the tips' - BIRDIE PUTTS.
If higher MOI is good for the other 13 utensils would it not follow that increasing MOI in the 'flatstick' would help on hits not made on the sweet spot? I believe I recently saw an ad claiming less loss of distance and line on 'off center' hits with this particular putter with 'high MOI'. I think everyone takes ads 'with a grain of salt', so here's your chance to give us the straight talk.
Oh, and thanks for the autographed copy of the book!
Dennis, NC.

Thank you for your kind comments and I am pleased that you enjoyed my book Just Hit It. I have been getting similar comments from many readers who are having fun and enjoying their game more than they have for some time. I do think, however, that we all have some work to do to make the introductory process to this wonderful game a little less intimidating and to get things changed to better accommodate those who have been in the game for many years but now finding it less enjoyable.
I hope that the last chapter will act as a call to action for golfers and operators to help us speed up play, offer nine-hole fees, install tees which are a more appropriate challenge for a wider range of golfing skills and other various other suggestions. I also try to help guide golfers through the process of proper equipment selection to help their game and their wallet. I also try to provide simple explanations of technical terms being used to sell equipment and which may or may not affect you game. But Dennis you already know this so I thank you for supporting our game and the cause.
Regarding higher MOI for putters, you are absolutely correct in your assumption. The original Ping putters introduced in the late 1960s, did exhibit a higher MOI ---- ( Click Here for an easy to understand explanation of MOI) --- than most other putters and were very popular because the off-centered impact was not as dramatically affected as with standard blade type putters with a lower MOI. For years we didnt change this design of toe heel weighting and many of todays custom putters are still of this Ping style.
Over the last ten years, however, the mallet putter has become popular and is something I recommend as it has a high MOI about two axes making it more forgiving on miss hits both up and down and from toe to heel. The effective sweet spot is thus bigger as evidenced by less of a fall off in distance on miss hits in two directions.
The Frankly Frog design is another step ahead of the standard mallet putter by having split weighting at the back to enhance balance and promote a smoother stroke by increasing the MOI about a third axes. This split weight concept in putters has now been copied by several major manufacturers which tends to prove that only true innovations are copied and also imitation is the best form of flattery.
Dennis, thanks again for your kind comments and I hope your experience with the book will encourage others to read it and start enjoying their game a little more.
Extinction of the 2 Iron
Someday I am going to splurge on a new set of irons. But I am afraid that by the time I do a 2 iron may not be offered in the set. I appreciate the benefits of technology, but I like my 2 iron. I use it off the tee almost half the time. Anyway, my question is whether it is possible to get an extra 3 iron and fold, spindle and mutilate it into a 2 iron, or is it too much difference in loft and lie?
Thank you very much.
Steve, PA


As much as you like your 2-iron I am afraid to let you know that it following the 1-iron on its way to taking a prominent place on the list of extinct clubs to be found in museums and attics of old houses or in the bags of some of us who just wont give up.
The fact is that you may need to replace it one of these days, or maybe not. The grooves on a 2-iron are almost inconsequential to performance of a 2-iron which has the loft of a strong 1-iron used in the days of Ben Hogan. So if you want to hang on to this club and you have really fallen in love with it and most importantly have developed confidence in it, then get it re-gripped and stay with it. The shaft will not wear out so it is going to be good for at least another twenty years or more as long as your performance remains constant.
If, on the other hand you are adventurous enough to even consider trying something else, which may ' and I emphasize may ' possibly perform as well as your 2-iron, then I do suggest that you sneak out without your clubs in the trunk to see what a 15 degree hybrid has to offer. It will probably have a little less loft than your 2-iron, and be about inch longer but when you hit it, you will find it will have a slightly higher trajectory than a 2-iron but so much more forgiving than your friend that you may even consider having a heart to heart with the 2-iron.
I know this is going to be very hard but it may be worth a try. Be careful how you let your 2-iron know when the time comes. It may ' if hurt ' start misbehaving.
Please dont try to turn an extra 3-iron into a 2-iron. It was not meant to be and you will be very disappointed and also lose a friend in you 2-iron which has stood by you for so long.
Obviously if you cannot make the leap to a hybrid then be assured that the two iron you have will continue to do its thing for many years.

Monty grabs lead entering final round in season-opener

By Associated PressJanuary 20, 2018, 4:00 am

KAILUA-KONA, Hawaii – Colin Montgomerie shot a second straight 7-under 65 to take a two-shot lead into the final round of the Mitsubishi Electric Championship, the season opener on the PGA Tour Champions.

The 54-year-old Scot, a six-time winner on the over-50 tour, didn't miss a fairway on Friday and made five birdies on the back nine to reach 14 under at Hualalai.

Montgomerie has made 17 birdies through 36 holes and said he will have to continue cashing in on his opportunities.

''We know that I've got to score something similar to what I've done – 66, 67, something like that, at least,'' Montgomerie said. ''You know the competition out here is so strong that if you do play away from the pins, you'll get run over. It's tough, but hey, it's great.''

Full-field scores from the Mitsubishi Electric Championship

First-round co-leaders Gene Sauers and Jerry Kelly each shot 68 and were 12 under.

''I hit the ball really well. You know, all the putts that dropped yesterday didn't drop today,'' Kelly said. ''I was just short and burning edges. It was good putting again. They just didn't go in.''

David Toms was three shots back after a 66. Woody Austin, Mark Calcavecchia and Doug Garwood each shot 67 and were another shot behind.

Bernhard Langer, defending the first of his seven 2017 titles, was six shots back after a 67.

The limited-field tournament on Hawaii's Big Island includes last season's winners, past champions of the event, major champions and Hall of Famers.

''We've enjoyed ourselves thoroughly here,'' Montgomerie said. ''It's just a dramatic spot, isn't it? If you don't like this, well, I'm sorry, take a good look in the mirror, you know?''

The missing link: Advice from successful tour pros

By Phil BlackmarJanuary 20, 2018, 1:24 am

Today’s topic is significant in that it underscores the direction golf is headed, a direction that has me a little concerned.

Now, more than ever, it has become the norm for PGA Tour players to put together a team to assist in all aspects of their career. These teams can typically include the player’s swing coach, mental coach, manager, workout specialist, dietician, physical therapist, short-game guru, doctor, accountant, nanny and wife. Though it often concerns me the player may be missing out when others are making decisions for them, that is not the topic.

I want to talk about what most players seem to be inexplicably leaving off their teams.

One of the things that separates great players from the rest of the pack – other than talent – is the great player’s ability to routinely stay comfortable and play with focus and clarity in all situations. Though innate to many, this skill is trainable and can be learned. Don’t get too excited, the details of such a plan are too long and more suited for a book than the short confines of this article.

So, if that aspect of the game is so important, where is the representative on the player’s team who has stood on the 18th tee with everything on the line? Where is the representative on the team who has experienced, over and over, what the player will be experiencing? In other words, where is the successful former tour player on the team?

You look to tennis and many players have such a person on their team. These teacher/mentors include the likes of Boris Becker, Ivan Lendl, Jimmy Connors and Brad Gilbert. Why is it not the norm in golf?

Sure, a few players have sought out the advice of Jack Nicklaus, but he’s not part of a team. The teaching ranks also include some former players like Butch Harmon and a few others. But how many teams include a player who has contended in a major, let alone won one or more?

I’m not here to argue the value and knowledge of all the other coaches who make up a player’s team. But how can the value of a successful tour professional be overlooked? If I’m going to ask someone what I should do in various situations on the course, I would prefer to include the experienced knowledge of players who have been there themselves.

This leads me to the second part of today’s message. Is there a need for the professional players to mix with professional teachers to deliver the best and most comprehensive teaching philosophy to average players? I feel there is.

Most lessons are concerned with changing the student’s swing. Often, this is done with little regard for how it feels to the student because the teacher believes the information is correct and more important than the “feels” of the student. “Stick with it until it’s comfortable” is often the message. This directive methodology was put on Twitter for public consumption a short time back:

On the other hand, the professional player is an expert at making a score and understands the intangible side of the game. The intangible side says: “Mechanics cannot stand alone in making a good player.” The intangible side understands “people feel things differently”; ask Jim Furyk to swing like Dustin Johnson, or vice versa. This means something that looks good to us may not feel right to someone else.

The intangible side lets us know that mechanics and feels must walk together in order for the player to succeed. From Ben Hogan’s book:

“What I have learned I have learned by laborious trial and error, watching a good player do something that looked right to me, stumbling across something that felt right to me, experimenting with that something to see if it helped or hindered, adopting it if it helped, refining it sometimes, discarding it if it didn’t help, sometimes discarding it later if it proved undependable in competition, experimenting continually with new ideas and old ideas and all manner of variations until I arrived at a set of fundamentals that appeared to me to be right because they accomplished a very definite purpose, a set of fundamentals which proved to me they were right because they stood up and produced under all kinds of pressure.”

Hogan beautifully described the learning process that could develop the swings of great players like DJ, Furyk, Lee Trevino, Jordan Spieth, Nicklaus, etc.

Bob Toski is still teaching. Steve Elkington is helping to bring us the insight of Jackie Burke. Hal Sutton has a beautiful teaching facility outside of Houston. And so on. Just like mechanics and feels, it’s not either-or – the best message comes from both teachers and players.

Lately, it seems the scale has swung more to one side; let us not forget the value of insights brought to us by the players who have best mastered the game.

Woods, Rahm, Rickie, J-Day headline Torrey field

By Golf Channel DigitalJanuary 20, 2018, 12:47 am

Tiger Woods is set to make his 2018 debut.

Woods is still part of the final field list for next week’s Farmers Insurance Open, the headliner of a tournament that includes defending champion Jon Rahm, Hideki Matsuyama, Justin Rose, Rickie Fowler, Phil Mickelson and Jason Day.

In all, 12 of the top 26 players in the world are teeing it up at Torrey Pines.

Though Woods has won eight times at Torrey Pines, he hasn’t broken 71 in his past seven rounds there and hasn’t played all four rounds since 2013, when he won. Last year he missed the cut after rounds of 76-72, then lasted just one round in Dubai before he withdrew with back spasms.

After a fourth back surgery, Woods didn’t return to competition until last month’s Hero World Challenge, where he tied for ninth. 

Woods has committed to play both the Farmers Insurance Open and next month's Genesis Open at Riviera, which benefits his foundation.

Even on 'off' day, Rahm shoots 67 at CareerBuilder

By Ryan LavnerJanuary 20, 2018, 12:36 am

Jon Rahm didn’t strike the ball as purely Friday as he did during his opening round at the CareerBuilder Challenge.

He still managed a 5-under 67 that put him just one shot off the lead heading into the weekend.

“I expected myself to go to the range (this morning) and keep flushing everything like I did yesterday,” said Rahm, who shot a career-low 62 at La Quinta on Thursday. “Everything was just a little bit off. It was just one of those days.”

After going bogey-free on Thursday, Rahm mixed four birdies and two bogeys over his opening six holes. He managed to settle down around the turn, then made two birdies on his final three holes to move within one shot of Andrew Landry (65).

Rahm has missed only five greens through two rounds and sits at 15-under 129. 

The 23-year-old Spaniard won in Dubai to end the year and opened 2018 with a runner-up finish at the Sentry Tournament of Champions. He needs a top-6 finish or better this week to supplant Jordan Spieth as the No. 2 player in the world.
