KENNY PERRY predicted the top players will handle the new grooves more easily than many have predicted. The new grooves are being used in tournament play for the first time at this week’s SBS Championship in Hawaii.

Perry does not agree that the new grooves will be a huge problem. “It will cause some problems but I don’t think it’s going to be a real big issue,” Perry (49) said.

“I think guys will adjust pretty quickly and you will still see good scores. I have struggled a little bit with my wedges. My sand wedges and stuff don’t bite like they used to bite, they want to release on out. But out of the fairway with my irons I haven’t noticed much difference at all.”

As of January 1st, new rules for club-face grooves were implemented at the top level after research found modern configurations could allow players to generate almost as much spin with irons from the rough as from the fairway. All clubs, with the exception of drivers and putters, have been affected by the change which limits groove volume and groove-edge sharpness, effectively replacing U-grooves with V-grooves.

Larger volume grooves can help channel away more material such as water or grass while sharper groove edges allow better contact between club and ball, thereby increasing the chance of backspin. “Chipping the ball is a big difference but even from the rough I have been hitting little jumpers, not big jumpers,” added Perry, a 14-times winner on the PGA Tour. “They are all great players out here and I think guys will adjust in a hurry.”

South Korean Yang Yong-eun, who won his first major title at last year’s PGA Championship after overhauling Tiger Woods in the final round, agreed. “I think it will be no problem,” Yang said. “Maybe this week, the first tournament of the year, there will be some problem but after three or four months of the players using these V-grooves they will be getting better.”

While most top players began experimenting with the new grooves toward the end of last year, it had been widely predicted that flyers from tangly rough would become a much more common occurrence on the leading tours around the world. “Previously with the squaregrooves, you’d get these certain lies in the intermediate cut (of rough) or in the rough where it’s questionable whether it was going to jump,” former Masters champion Zach Johnson said.

“Now it’s not questionable; you know it’s going to jump. It’s just a matter of how much it’s going to jump. It’s not an advantage. It’s just the way it is.”

Yang felt next week’s Sony Open could present a stiffer test for the players because of the harder, smaller greens at Waialae Country Club. “This week we have big fairways and therefore it’s easier to avoid the rough,” Yang said of the PGA Tour’s season-opening event being held on the Plantation Course. “And with 100 (yard) shots, 150 shots there is a lot of spin because the greens here are a little bit soft. The loft may be a little bit different but the ball is still spinning.

“But next week, at the Sony Open on hard greens, maybe it will be very different.”

Many golfers get confused about which club to hit from the fairway. They are thinking to themselves, “my 7 wood, 3 iron and 3 hybrid are all 21 degrees loft, which is the right one?”

What they forget, or were not aware of in the first place, is that loft is only part of the distance equation. The three major variables for club distance are loft, length and weight. In the case cited above, the 7 wood is the longest club, and the 3 hybrid and 3 iron are normally the same length. Weight-wise, the 7 wood is the heaviest, 3 hybrid in the middle, and the 3 iron is the lightest.

Golf Digest reported that hybrids averaged about 8 yards longer than same numbered iron.  I am sure this information was based on many OEM hybrids that are built ½” – 1” longer than an iron as well as lofts that are often 1-2 degrees stronger than the corresponding iron.  Remember that hybrids more often than not are assembled with graphite shafts.

You’ll also need to be aware that these clubs may produce varying trajectories. For instance the typical hybrid shaft is less flexible in the tip than a corresponding iron shaft, thus producing a lower trajectory.

The Bottom Line
Concentrate on replacing a club that you are not hitting well or fill any yardage gaps you might have, but don’t necessarily go by the number engraved on the sole. Think about the loft, length and weight.  A lower (stronger) loft will hit the ball farther, but a shorter assembly length will reduce speed and distance. It is possible to carry two clubs with the same or similar lofts, that fly different distances, and at different maximum heights.

Have you ever wondered why your graphite shafted driver is longer than your old steel shafted model? There’s a logical reason. Here’s a good explanation in an article posted on 24 June 2008 by Jeff Summitt of Hireko Golf.

Swingweight Plays A Major Part In This Equation

Often times when you look at the published length of a golf club it will list two lengths for men and possibly two for women if the manufacturer has steel as a shaft option.  Yet in all these cases they will be listed as “standard” length.  This may seem confusing to Read the rest of this entry »

Shaft torque can be difficult to explain. Engineers will understand it, but many golfers do not. So, I looked for an article that puts it in the simplest form for all to grasp. I hope this one helps.

A Lesson In Golf Shaft Torque Values

What is shaft torque?
It is the amount a shaft twists when subjected to a known amount of force (usually one foot-pound of force is applied) and the value expressed in degrees. It is a term commonly associated with composite or graphite shafts, but steel shafts have a certain degree of torque too. However Read the rest of this entry »

The new groove rule has created a great deal of confusion, and the manufacturers have added to the confusion in their quest to sell their clubs. So, here is a boiled-down summary of what the rule means to you and me, the average-joe golfers.

The following from Dave Pelz is a good summation Golf.com(Feb. 26, 2009):

“The USGA has created a new rule to limit the backspin performance of grooves on lofted clubs. The rule downsizes groove volume and limits edge sharpness for all grooves manufactured after January 1, 2010 so they’re equal to or less than the previously approved V-groove dimensions. PGA Tour players must use wedges conforming to the rule beginning 1/1/10. The ruling will decrease backspin and increase stopping distances pros typically achieve from grassy lies, and place more of a premium on hitting fairways.

How does the new rule affect you? If you’re an amateur who wants more backspin, you realize the grooves you play determine the third factor in your backspin equation and the stopping Read the rest of this entry »
