11.6 Fit Your Putter (选择合适的推杆)

*** Golfers’ Grips (如何握杆)

The most common is the “parallel-palm” grip: holding the grip along the lifeline of your left hand, instead of in the fingers helps the putter function as part of your arm and decreases the tendency to supply power with your hands. Keeping the palms parallel to the face of the putter also makes it easy to keep your forearm flow-line in good position.

Something else, which very few people talk about, is spreading the hands apart on the grip. The farther apart they are, the less active the wrist muscles in the stroke, which explains some of the success of the long putter. But spreading the hands also makes it difficult to coordinate the actions of the arms, so it is impractical on a standard-length putter.

There are many acceptable ways to hold a putter, such as the “reverse-overlap,” “finger-down-the-shaft,” “split-grip,” “equal-hand,” and “baseball” grips. I suggest that you test and evaluate a few grips as you work to improve your stroke mechanics. Sometimes changing a grip can affect the path and face angle of your putter through impact.






*** Unusual Grips (奇特的握杆)

Many players have found less conventional grips that work for them. These grips may be different, but they have proven comfortable and consistent. Take for example, Corey Pavin’s “opposed-palm” grip. Corey’s problem used to be missing to the left. He pulled putts until he turned his left hand as far left on the putter as possible, which stopped the pulls because he couldn’t turn his left forearm any further left during his stroke. But then he started pushing putts to the right. The solution was obvious: Turn the right hand as far to the right as possible. So with his palms “opposed,” he became a very fine putter, wining the 1995U.S. Open putting that way.

While I said above that no one grip is best for everyone, “left-hand-low” ( which really should be called “lead –hand-low”) is one that I suggest every golfer try. Left-hand-low places the right forearm on-line with or slightly below the ideal forearm plane, taking the right arm out of the “powerful position” and allowing the left arm to lead or pull the stroke through.





*** Putter Grips (握把)

The size, shape, and orientation of the grip on your putter should be appropriate for the size of your hands, allowing for a comfortable hold and a feeling of control. It is extremely important that it be installed squarely and correctly, not the slightest bit crooked or twisted which would create an incorrect face angle at impact even if your hands were positioned perfectly square to the Aim-line.


*** Head Weight (杆头重量)

The head design of the putter you select should be compatible with your ability to align it, hit it solidly, and have a good feel for distance with it. Heavier putter-heads encourage golfers to swing more slowly, sometimes leaving putts short; however, heavier heads are good if your hands tend to be overactive during the stroke. Light putters give golfers with pendulum strokes a better feel for distance; but in the hands of a golfer with a handsy stroke, a lighter head can be a disaster.


*** Shaft Flex (杆身硬度)

Most golfers never consider the flex of their putter shaft, but it is something that can help, or hurt, you success. Ben Crenshaw uses a very weak and flexible shaft, because he wants to feel when his putter-head is in perfect rhythm with his stroke. Most graphite putter shafts, which are both flexible and light, help do this, too.

Another great putter, Deane Beman, pioneered a completely different line of thought. Deane wanted the stiffest, strongest shaft he could get, so the shaft wouldn’t add or subtract any energy he didn’t want.

To determine which shaft suits you, test them on very long putts and see which provides you with the best touch and feel for distance.




*** Loft Angle (杆面角)

The effective loft of your putter is what determines where your putter makes contact – above, on, or below the ball’s center of mass.

This point of contact combines with the angle of approach of the putter to determine the initial launch conditions of your putt. And yes, putts do “launch”: Depending on how they are struck, they can launch down into the surface of the green, skid horizontally across the green surface, or launch upward – and do any of those with backspin, over spin, or no spin at all.

I recommend that you launch your putts ever so slightly upward, to get them on top of the grass as quickly as possible, without giving them so much loft that they bounce on the green. One or two degrees of loft – relative to the surface of the green through impact – is usually enough.




*** Face Material (杆面材料)

At the Pelz Golf Institute, we have a pet theory that the best putter would have the softest face. This theory is based on our knowledge that the ball follows the face-angle direction of the putter at impact more closely than it follow putter-path direction, while golfers have more control of the putter path. So if softening the face would help the ball follow the putter path more closely, then softer faces would give the golfer more control.

I’m very comfortable saying that while soft-faced putters may feel and sound better, those on the market today won’t make large differences in the direction your putts roll if these faces do have a significant benefit other than a more solid sound, it’s probably in lessening the dimple effect.

Run your own tests of different putting material to see if one works better for you on short putts while preserving your feel for distance on long putts.




*** Comfort(舒适度)

This is often overlooked element of putter-fitting, because many golfers don’t think it’s about the putter at all. However, the more comfortable you are while practicing putting, the longer you’ll practice and the better your putting will become (assuming you’re practicing properly). Your putter should be fit so you can be physically comfortable enough to practice sufficiently to learn to love and trust on the course.

Another kind of comfort is how much you like the way a putter looks.



*** Commitment (承诺)

You must commit to, practice with, and stay with a putter for an extended period of time before it can become your best friend.

Picking up a new putter every day, every week, even every month will do you more harm than good. If you think the problem is in the putter, have a competent golf professional properly fit the club to you, your body, and your stroke. Then-and this is key-commit to the club to learning a better stroke with it than you ever had before. Once you learn a better stroke, keep your commitment to groove itand finally, own it.



11.7 Learn to Aim (瞄准)

Alignment is the first fundamental of putting stroke mechanics; if you can’t aim your putter and stand to your Aim-line properly, you have little or no chance of making a repeatable pure stroke. To improve, you must always correct two things, the mistake and its compensation (correct only one thing and you’ll probably putt worse).


*** The “Lazr-Aimer” (激光瞄准仪)

The most efficient way to teach your brain what perfect putter alignment looks like is with a device called the Lazr-Aimer. The Lazr-Aimer shines a low-power laser beam onto a small mirror attached to the putter face. After aiming the putter at the Lazr-Aimer to the best of your ability, you say “on” to voice-activate the beam, which turns on for a few seconds, bounces off the putter-face back to the wall, and shows an error in alignment.

Golfers who practice with this device dramatically improve their ability to aim, seeing result in as little as five minutes. However, by the next day, most of that improvement has disappeared. Our experience shows that it takes about three weeks for improvement to make it to the golf course.




*** Aim in the Putting Track (推杆轨道)

The Putting Track is the poor man’s Lazr-Aimer. It can be very effective improving a golfer’s ability to aim, but it takes much more time, as long as six months.



*** Aim the Balance-line以平衡线为瞄准线

Many golfers improve their alignment by first aiming a line (or the printed words that form a line) on the golf ball in the direction that they want the putt to start. With the line properly aimed, they set the head of the putter perpendicular to that line as they address their putts.

Back in section 9.8 I showed that a ball rolls straighter along its Aim-line if it is rolled on its “Balance-line”. I have been recommending for years that golfers measure and mark their balls this way, then position them for putting with their Balance-line vertical and aligned directly along the Aim-line. It will help the putt roll straighter, and also serve as an alignment aid.




*** The Putter Face-Line (球面圈)

The Putter Face-line is a circle, centered on the Dot-stop and perpendicular to the Balance-line, which mean it will appear parallel to our putter-face when the face is aimed square down your Aim-line.



*** The Dot-Spot

The “Dot-Spot” (the largest area of non-dimpled surface) is usually one of the two places on every ball where the Balance –line crosses the seam: Every ball has a seam in its cover where the two halves are joined, and there’s usually a little more surface area along that line than on the rest of the dimple-covered ball.
