I disagree With MyGolfSpy.com.

Read below and you’ll see that Jim McKay, President OnePutt Enterprises* didn’t agree with the MyGolfSpy test on Stability. Specially, he didn’t not agree with their testing methodology or conclusions.

My thoughts…
The golf equipment industry is replete with “carefully worded” promises on equipment performance.
Our little company, Breakthrough Golf Technology may be new but, we have 200 years of specific golf industry experience among our employees. Specifically, we know golf and we definitely know how to test. I stand by our claims that Stability is far superior to 50-year-old steel shaft technology. I encourage you to review the test and Jim’s rebuttal to the test and make your own conclusion.

*OnePutt Enterprises is the premier independent putter testing and consulting company. It’s at the forefront in advancing ideal testing methodologies for putters, developing improvements in putter face technology, putter head design, and shaft technologies.

First, I hate it when non-scientific people pretend to be scientific when trying to run a test. MyGolfSpy said they were scientific in using the exact same putter head with a steel and stability shaft to run the test. Wonderful start if your using a robot but not good if you are using real people. Why, because that one putter (loft, lie, length, swing weight, toe hand, etc…) isn’t the proper fit for all those people, it may not have been the proper fit for any of them. If you have Tiger Woods & Bubba Watson test two different driver shafts that are both a weaker senior flex, the superior shaft wouldn’t stand out. If MyGolfSpy was doing a driver shaft test and had men and women of different ages and handicaps, would they all have them hit the same flex driver, of course not. We would have no respect for the results if they did. By using just the one putter, it shows just how little they understand and know about putters.
With real people, you need different lengths, lofts, toe hangs, grip sizes, etc. in matching sets. In other words, they should have had 10 – 20 sets of varying Bettinardi putters so the testers could use the putter that was right for them, not one set that might not be right for anyone. If a player uses a face balanced putter, they are not going to putt as well with a putter with toe hang and vice versa. Same thing applies for length, grip size, lie angle, loft, etc… .
Moving beyond that, they used a launch monitor to collect data, great. The problem is they only used it for the 10′ putt. If you’re going to be scientific, you need to use it for all the putts. They were testing the claim that the stability shaft is more stable. The longer the putt and the harder you swing the putter, the more force you create. To show (or disprove that claim), it’s only common sense that you need to collect the data at each distance. The test showed that the start direction and consistency (standard deviation) was better with the stability shaft on the 10′ putt. Had they simply collected the data for 5′ and 20′ as well and it showed a progressively larger start direction improvement and standard deviation, it would have proven the shafts claims.
They talk about face impact position, again, only on a 10′ putt, and how the stability shaft is .03 and steel is .41. That difference is very large and will affect impact ratio and therefore distance control. How much larger might that be on the 20′ putt?
The visual results that they captured were only make or miss; there is nothing about distance from the hole on missed putts. Out on the golf course, from 20′, missing it by 1′ is far different than missing it by 5′, but for their testing it’s all the same. On the PGA Tour, which are the very best golfers in the world, the average is 12% putts made from 20′ – 25′. The proximity to the hole is far more important than the putts made from that distance but they didn’t collect any data on that.
MyGolfSpy makes the comment in their observations, 10′ is the most important distance that they test in putting, why? Statistically, there is no valid reason to make that claim. Again, going back to PGA Tour data, 8′ is where the significant drop off in make/miss is. The average 1st putt for greens in regulation is over 25′. Players average almost 10% 3 putts outside of 25′. These are the numbers from the very best players in the world, how much worse is the average golfer? That claim of 10″ being the most important distance makes as much sense as using one putter for 10 different people.
MyGolfSpy created a testing situation that isn’t what actually happens on the golf course. On the golf course, you get one chance on a putt, you don’t get to do it 10 times in a row and learn from each previous putt. The putts that you have on the course are a variety of breaking putts (as well as uphill and downhill), and where a miss ends up matters.
The testing showed significant differences between the stability shaft and steel, but because of the major flaws in both their testing and observations, couldn’t distinguish the value of those differences.
If MyGolfSpy wanted to do a true, proper test, they should have given the players a variety of putter heads, lengths, and grips to choose from that could then be adjusted to proper lie and loft, they should have used the launch monitor to collect data at every distance, they should have collected the results of distance from the hole on missed putts, and they should have had an equal variety of breaking putts in both directions included in the ten putts at each distance. The results of that test would show the real difference between the stability shaft and steel.
