Chuck Brown,
I've said pretty much exactly the same thing as you about the difference in technological progress between changes that allowed the equipment to be cheaper, of a more consistent quality, or more durable. I'm fine with stuff like steel shafts replacing hickory (wins on all three counts) metal woods replacing persimmon (wins on two) or solid balls with synthetic covers (wins on 2 or 3 counts)
But like you say, pretty much every change since metal woods were introduced have only made the equipment more expensive to manufacture or decreased its durability (i.e., cracked faces in Ti drivers, more easily damaged graphite shafts) They've been about de-skilling the game, especially off the tee. It used to be that the driver was the most difficult club in the bag to master, now it is the easiest.
Paul Turner,
I'd agree that changes to the driver have had more impact on the in terms of greatly diminishing the skill required to hit a driver off the tee. I don't mean it is easy to hit it straight, but it IS easy to hit it relatively solid which wasn't always the case. I see plenty of beginners who can hit the driver off the tee reasonably well, but can't hit the ball off the ground to save their life. It used to be exactly the opposite when I was a kid back when metal woods were just beginning to make their appearance. The majority of golfers didn't even carry a driver, or carried one around but never used it.
But if you are claiming that the modern driver has been been primarily responsible for the increase in distance we've observed over the last 10 years, then I'd have to strongly disagree. As I've posted here before, I dig out my persimmon driver every now and then, and when I last did 4 or 5 years ago I didn't see much difference between it and my big headed Ti driver in distance off the tee. When I hit it perfectly solid, that is (when I don't, oh boy is the difference noticeable!)
Now keep in mind that I've always hit the ball very high so getting the proper trajectory with that old driver would be easier for me than for most people, plus my Ti driver is only 44.25" long which is shorter than most people's 45" or even 46" so it wasn't as big of a difference from the 43.25" steel shafted driver. Plus I'm pretty strong so the fact its heavier probably isn't influencing my swing speed all that much. I think the reason most people might see more of a difference is just that their circumstances aren't as optimal as mine happen to be.
