I spoke to them about a week ago and reported on here what they said about how the distance increase relates to the golf ball in the last 10-12 years. You can believe what you hear on here from someone who tries to analyze PGA Tour statistics and relies on hypothetical graphs and such he creates himself . . .
You’ve got this wrong here, Tom. The basic assumption behind my chart (linear distance increase with increased ball speed) came from your report on what the USGA told you. And f you doubt the pertinence of my chart, I suggest you take a look at JohnV’s analysis. Had he transferred his numbers to a chart you would see that his numbers parallel mine and demonstrate the same point. Surely you aren’t suggesting that JohnK is doubting or ignoring the USGA’s expertise on this, are you?
In the last 20-25 years COR increased from app .078 to .086 and has now been limited to .083.
Your analysis here is about the COR of clubs and ignores the COR of the ball, which is crucial to understanding what is going on with these new balls.
The new-age ball is really nothing more than a significantly lower spin rate ball than the elite players (big hitters) used to use up until about ten year ago that feels almost as "soft" to them as the old much higher spin rate three pieces wound ball they all used to use which simply did not go as far as either the new age balls OR the old low spinning two piece (Hard) ball that's been around for over 40 years. They never used that old low spinning ball (Pinnacle type) simply because if felt too hard to them around greens.
This strikes me as accurate and I have been assuming so throughout these discussions. But let’s be clear that it was
NEW TECHNOLOGY (mainly in the form of new materials and a 3 piece ball) ] that made the switch to low spin balls possible for the better players. The old Pinnacles balls may have gone far at high swing speeds, but for the better players they were like a race car with no steering wheel or breaks . . .
NO CONTROL. The reason the old high spin rate three piece wound ball did not go as far for big hitters is because of its trajectory which was not the distance enhancing trajectory of the new age ball OR THE OLD HARD BALL. (As an example the USGA Tech Center said last week that if a Davis Love hit an old low spinnng two piece hard ball (like a Pinnacle) with his equipment today it would go about as far as the ball he uses today (ProV series).
A large part of the reason was the balls really spun so much at higher swing speeds that they would balloon and lose distance. You have said as much when you described the old players hitting a ball which would start out low and then rise like a jet. That is spin creating lift, and if there is too much lift, distance will be sacrificed.
As for Davis Love III, he may have been able to hit a Pinnacle almost as far as the ProV1x (assuming modern club technology,) but he would never have done so because he could not control such a ball. So instead he took a smooth swing at a ball he could control. He had no other realistic option.
This is precisely why I asked David Moriarty if he knows how much farther the low spinning ball (the old Pinnacle or the new ProV) goes if hit at 109 mph compared to the old high spinning ball all the elite players used to use until about ten years ago. Apparenly he doesn't understand the significance of the question. The significance of the question is---what if all the elite players hit the old two piece hard ball as most all handicap players did starting about 40 years ago?
I don’t think this question has the significance you place upon it, but instead raises quite the opposite point.
There was a very good reason that the better players did not use hard two-piece balls:
Forty years ago, the better players could not control the Pinnacles, especially at high swing speeds. In other words,
40 years ago these low spin, hard cover balls were not yet technologically advanced enough to be of any practical use to the better players-- especially with 1966 woods. But much has changed technologically in the past 40 years to clubs, balls, and optimization. So now Davis Love III can hit the low spin ball and reap the distance benefits that were not a
realistic option before. More significantly for this discussion, the new technology (including balls, clubs and their optimization) also allows him to swing much harder than he ever could with a soft, high spin ball.
Would he then conclude that the distance differential between power hitters and average hitters got out of balance 40 years ago instead of recently? And does he think the distance differential was in balance during those app 30 years when basically all long hitters and all average hitters used two entirely different types of ball but it's now out of balance when they use the same type of ball?
Had the modern technology (the clubs and balls and optimization) happened forty years ago then YES, it the game would have gotten out of balance 40 years ago.
And YES, the game was much more in balance 30 years ago because low ball spin technology was then in its infancy—they were decades away from designing and producing a
controllable low spin ball for better players.
Basically George you can believe what the USGA Tech Center says about ball and club performance. Essentially probably no one knows it better than they do. That's what they do. That's what they're there for.
This is where you lose me, Tom. I think everything I am saying is in complete agreement with your report of information from the USGA. If I am mistaken about this, then I’d really appreciate if you or someone else could specifically tell me where what I am saying is in contradiction to what the USGA is saying.
