Do Lighter Grips Improve Your Distance

By Frank ThomasJanuary 15, 2010, 7:43 pm
Dear Frank

Recently a major golf grip manufacturer advertised grips which are about half the weight of normal grips.  The theory is that this will increase clubhead feel, accuracy, and clubhead speed.

Is there any merit to having my irons regripped with grips that are about one half the weight of normal grips?  Will the average 15 handicap golfer improve his feel and game with lighter grips, or is this simply more marketing hype?


– Bernie, Canada

Isn’t it surprising how the minds of marketing  people work? We have been making golf clubs for about 400 years and somehow believe that we can come up with some new discovery which will increase, distance – the most effective word in golf marketing – and improve accuracy. Feel is  something nobody has satisfactorily defined – but we all know what it means; Or do we?  These claims of increased distance, accuracy and feel are the food we gullible golfers thrive upon, and almost without question.

Looking for the magic potion, which will solve our golfing woes, is in itself an addictive and charming part of the game.

The “looking” part, in anticipation of finding the magic, makes this activity very addictive, but not the actual “finding” part. If we ever found the magic club our search would be over. We would have nothing to look for. The excitement and charm of this search would be over.  

Because golf is such a mental game influenced so much by what we believe, it lends itself to building fantasies only to have these knocked down time after time, and not to our surprise. We know that there is no magic but this does not stop us from looking for it, and there is a lot of it for sale.

If you decrease the weight of the average grip by 50% you will increase the swing weight by about 7 points.
This is the same as removing a heavy golf glove if you use a glove – which might as well be part of the grip – or even if you remove your wristwatch.

Because the weight has been removed from the axis of rotation during the critical part of the swing – just before impact – it has little effect on the dynamics of the club. I discussed this in a Q&A recently about wearing a golf glove.

Swing weight is not a dynamic balance, as the name implies. It is based on a static balance and in technical terms described as “first moments”. This means that to balance a beam you need to add a weight to one side at a certain distance from the fulcrum (balance point) and an equivalent amount of weight to the other side at the  same distance or half the weight at twice the distance. Through this balancing procedure a telephone pole can be “swing weighted” to D2 the same as our driver. But the overall weight is significantly different.

A method of dynamic balancing would be to match clubs using  Moment of Inertia (MOI) by oscillating it back and forth about the axis of rotation in the critical region of the swing – a point a little above the hands. MOI is a measure of the resistance to angular acceleration, which means the forces required to twist or stop twisting around a specific axis.

To calculate the approximate MOI, the head mass is multiplied by the square of the distance to the center of the head from the axis of rotation. So if you add or subtract mass – decrease or increase the grip weight – from the axis of rotation the MOI doesn’t change very much. And we all intuitively know this – i.e. taking your glove off or decreasing the weight of the grip doesn’t make much difference to performance but it does change the swing weight by five or six points.

This is why MOI balancing is a much better method than swing weight for balancing a set of clubs – certainly if swing weight is manipulated by back weighting etc. MOI is a dynamic balance and clubs so balanced will be close to the PURE swing weight balancing as it was originally developed based on Francis Ouimet’s set (first amateur to win the US Open in 1913 at 20 years old). This set was assembled by Francis Ouimet based on club feel with length and head weight being the only variables and the results closely match MOI matching.

Sorry about this but I thought it needed to be explained.

Hope this has helped you understand that magic is hard to find but searching for it is fun.

Winning on Kerr's mind this week and beyond

By Randall MellMarch 24, 2018, 2:11 am

Cristie Kerr moved into position Friday to do more than win the 21st LPGA title of her career.

She moved into position to claim an LPGA Hall of Fame point this week.

Yes, winning is foremost on her mind at the Kia Classic, where she took the lead with an 8-under-par 64 in the second round, she’s on a larger quest, too.

After turning 40 last fall, Kerr was asked what her goals are.

“The Hall of Fame is attainable, if I stick with it,” she said.

Kerr is five shots ahead of Lizette Salas (67), In-Kyung Kim (69), Hee Young Park (70) and Caroline Hedwall (70).

It’s a good time for Kerr to get on a hot streak, with the year’s first major championship, the ANA Inspiration, next week. She has long been one of the best putters in the women’s game, but her ball-striking is impressive this week. She hit 17 greens in regulation Thursday, and she hit 16 on Friday.

“I like winning,” Kerr said. “I like challenging myself. Definitely doesn't get any easier as you get older, with the travel and recovery time. I got up this morning and I'm like, `Man, why does my hamstring hurt?’ From working around this hilly golf course.”

Kerr acknowledged Friday that her body is more vulnerable to time’s realities, but her mind isn’t.

Full-field scores from the Kia Classic

“The golf ball doesn't know an age,” Kerr said. “I've always said that. As long as I stay hungry, going to just keep playing.”

Kerr won two weeks after her 40th birthday last fall, boosting her LPGA Hall of Fame point total to 22. She is five points short of eligibility for induction. A player earns one point for an LPGA victory and two points for a major championship title. So there’s a lot of Hall of Fame ground to gain this week and next.

It’s a long-term goal that motivates Kerr to take care of her body.

“I don't think the golf changes,” Kerr said. “I think, physically, it gets harder as you get older. Like I said, I've got tape on my hamstring. I strained it, just a little bit yesterday, walking around this golf course. It's tough as you get older, just being fresh and rested. I put more focus into that as I've gotten older. I still practice, but off the course I try to get more rest.”

Big names chasing Kerr into the weekend at Kia Classic

By Associated PressMarch 24, 2018, 1:55 am

CARLSBAD, Calif. - Cristie Kerr shot an 8-under 64 on Friday in the Kia Classic to take a five-stroke lead into the weekend.

The 40-year-old Kerr had eight birdies in her second straight bogey-free round to reach 13-under 131 at rain-softened Aviara.

''I like winning. I like challenging myself,'' Kerr said. ''Definitely doesn't get any easier as you get older with the travel and recovery time. I got up this morning and I'm like, 'Man, why does my hamstring hurt?' From working around this hilly golf course. The golf ball doesn't know an age. I've always said that. As long as I stay hungry, going to just keep playing.''

She has 20 LPGA victories, winning at Aviara in 2015. She won twice last year and helped the U.S. beat Europe in her ninth Solheim Cup appearance.

''It's tough as you get older just being fresh and rested,'' Kerr said. ''I put more focus into that as I've gotten older. I still practice, but off the course I try to get more rest.''

Lizette Salas, In-Kyung Kim, Hee Young Park and Caroline Hedwall were tied for second. Salas shot 67, Kim 69, and Park and Hedwall 70.

''I really like this golf course. I really like the environment,'' said Salas, the former University of Southern California player from Azusa. ''My family gets to come out. So much confidence at the beginning of the week, and definitely showed the first two days.

Jeong Eun Lee was 7 under after a 69, and defending ANA champion So Yeon Ryu had a 70 to get to 6 under.

Full-field scores from the Kia Classic

Ariya Jutanugarn (72), Brooke Henderson (70) and 2016 winner Lydia Ko (71) were 5 under. Shanshan Feng (68) was another stroke back, and Singapore winner Michelle Wie (72) was 1 under.

Lexi Thompson was 2 over after a 74, making the cut on the number in the final event before the major ANA Inspiration next week at Mission Hills.

Kerr opened with birdies on the par-5 10th and par-3 11th, added birdies on the par-4 16th, 18th and second, and ran off three in a row on the par-3 sixth, par-4 seventh and par-5 eighth.

''I don't think you can fall asleep on one shot,'' Kerr said. ''It's a really good golf course. I think I play better on courses that demand the focus, so I think that's why I've played well here in the past. ... I'm trying not to put limits on myself right now. I've got some good things going on with my swing.''

She has long been one best putters and green-readers in the world.

''I can see the subtleties that a lot of people can't,'' Kerr said. ''It's a gift from God being able to do that. I've always had that, so I'm lucky.''

Laura Davies withdrew after an opening 82. The 54-year-old Davies tied for second last week in the Founders Cup in Phoenix, playing through painful left Achilles and calf problems.

DJ hits 489-yard drive, but it doesn't count for history

By Rex HoggardMarch 24, 2018, 12:22 am

AUSTIN, Texas – Dustin Johnson is no stranger to big drives, but even for DJ this one was impressive.

Trailing in his Day 3 match at the WGC-Dell Technologies Match Play, Johnson launched a drive at the par-5 12th hole that traveled 489 yards, but that number comes with an asterisk.

“He got lucky it hit the road,” smiled Kevin Kisner, who was leading the world No. 1, 3 up, at the time. “I thought he would make an eagle for sure, he only had 80 yards [to the hole]. He didn’t hit a very good putt.”

Johnson’s drive, which was 139 yards past Kisner’s tee shot, is the longest recorded on the PGA Tour in the ShotLink era, surpassing Davis Love III’s drive of 476 yards in 2004 at the Tournament of Champions.

The drive will not go into the record books, however, because the Tour doesn’t count statistics from the Match Play.

It should also be noted, Kisner halved the 12th hole with a birdie and won the match, 4 and 3, to advance to the round of 16.

Durant leads Champions event in Mississippi

By Associated PressMarch 24, 2018, 12:21 am

BILOXI, Miss. - Joe Durant had three straight birdies in a back-nine burst and a shot 6-under 66 on Friday to take the first-round lead in the PGA Tour Champions' Rapiscan Systems Classic.

Durant birdied the par-4 11th and 12th and par-5 13th in the bogey-free round at breezy and rain-softened Fallen Oak. Because of the wet conditions, players were allowed to lift, clean and place their golf balls in the fairway.

''It just sets up nice to my eye,'' Durant said. ''It's a beautiful golf course and it's very challenging. The tee shots seem to set up well for me, but the greens are maybe as quick as I've ever seen them here. You really have to put the ball in the right spots. I played very nice today. With the wind swirling like it was, I'm really happy.''

He won the Chubb Classic last month in Naples, Florida, for his third victory on the 50-and-over tour.

''Done this long enough, Friday's just one day,'' Durant said. ''Especially in a three-day tournament, you've got to go out and shoot three good numbers. Fortunate to put one on the board, but I know I have to back it up with a couple of good days because you can get passed very quickly out here.''

Mark Calcavecchia was a stroke back. He won last month in Boca Raton, Florida

''It's probably my best round I've ever had here and it was a tough day to play,'' Calcavecchia said. ''The greens are just lightning fast. They're pretty slopey greens, so very difficult to putt.''

Steve Stricker was third at 68. He took the Tucson, Arizona, event three weeks ago for his first senior victory.

''Just getting it around and managing my game I think like I always do,'' Stricker said. ''You get in the wrong position here with the greens being so fast and you're going to be in trouble. I did that a couple times today.''

Billy Mayfair, Billy Andrade and David McKenzie shot 69. Jerry Kelly, the winner of the season-opening event in Hawaii, was at 70 with Wes Short Jr., Glen Day, Gene Sauers and Jesper Parnevik.

Bernhard Langer opened with a 71, and two-time defending champion Miguel Angel Jimenez had a 72.

Vijay Singh, coming off his first senior victory two weeks ago in Newport Beach, California, had a 73.
