Here's some of what was said re: distance
(first though) I should clarify something I just posted--when I said the US Open was NEVER sponsor free I should have said that as early as the 1950s the USGA accepted sponsorships in return for advertising.
Mr. Driver seemed top "blame" the distance explosion on three things:
1. The Ball--Mr. Driver claimes that around 1998 everything changed when companies were able to combine one piece distance with cover technology that allowed better players to work and spin the ball. Prior to 1998, pros could have played pinnacles but they were willing to trade off distance for control. This represented about an 18 yard gain when the Pro V1 essentially replaced the Tour Balata--the last wound ball.
I am a little fuzzy here but I think what he said was that the tolerances allowed when pinnacles and other hard balls "passed" was +/- 6% since reduced to +/-2%. To go back and use todays threshold on the older hard balls as part of the overall distance standard would be to make 67% of all balls on the market today illegal. Further, if the solid core/soft cover ball were made illegal and players were forced to return to wound balls, guess who is the only company with the current capability to manufacture a wound ball--titleist!!! Also, guess who still owns all the patents on wound balls! Would you want to give Titleist this monopoly? How long till the lawsuits started flying.
Also, the players on the PGA tour are almost unanimous in their opposition to this. Most guys on tour are under 30 and have NEVER played with a wound ball. They would scream that they would be at a competitive disadvantage vis-a-vis older players. Remember, the tour (and everyone else) voluntarily complies with the Rules of Golf. They could literally make up their own competition rules if they wanted--then you'd have "tri-furcation"--luddites like me playing permismon and wopund balls (maybe 1% of golfers), tour pros playing all the rules except equipment rules (1% of golfers) and the other 98% would continue playing whatever they can buy and pretty much cheating--winter rules, mulligans, etc...
The tour is a UNION and those young guys make too good a living with the current equipment to consider any equipment rollback that MIGHT harm their ability to rake in millions every year.
2. The clubs--in an attempt to maximize the sweet spot by increasing club head size and also intoducing new materials like titanium, manufacturers essentially backed into an increased coefficient of restitution (COR) or "sprig like effect". Back in the late 90's the USGA was behind the curve and could do nothing other than cath-up. They have vowed to produce testing facilities which are second to none and believe they will lead the industry in terms of research and understanding what is going on re: the physics of hitting a golf ball. (More reason to have a war chest--to always stay ahead rather than trying to catch up.) Also, to turn back the clock on clubs that have already been issued letters from the USGA/R & A that acknowledge their conformity would be to declare more than 6 million clubs non-confroming. How happy would golfers be who purchased those drivers given that they were legal when purchased? Clubs have accounted for about 8-10 additional yards since 1998
3. The players are (sorry Geoff S.) bigger, stronger, more athletic and just better at generating incredible club head speed than ever before. It is club head speed that essentially determines how far the balls can go. Mr. Driver disputed the notion that better players disproportionately benefit for technology. He claimed that distance is a function of clubhead speed (all other things being equal--solidness of contact, mass of the club) and if you take away 10% of the distance from a pro, you will take away 10% of the average players distance too. No magic ball exists that leaves an average guys 225 yard drive alone and throttles back Tiger to 280.
Regarding balls and club regulation, I am very sad to say that the "horse has left the barn" and there's no way things will ever go back. Best we can hope for is that now with the finest testing facilities in the world, the USGA can stay ahead of the manufacturers and keep the status quo going forward.
Sorry I don't have better news
BTW I found Mr. Driver an excellent and engaging speaker and he certainly seemed like he knew what the hell he was talking about--I'm glad I got to hear the "other side" straight from the horses mouth!
