BCrosby,
In my own experience, I find that it is harder to "move" the ball today, that equipment and the ball require a more exaggerated effort to influence the flight of the ball.
Therefore, I conclude, that you can swing harder, with less fear of substantial ball flight deviation.
But, when the ball is on the turf, that's a more difficult shot, although perimeter weighting has helped.
I also think that many golfer focus on the "big blast" with the driver, at the expense of the rest of their game.
I can't tell you how many times when I'm at the range, that I observe golfers come to the range, and the first club they take out to practice with is their driver.
I know a lot of golfers whose handicaps went down with the acquisition of a high tech driver in the last 10 years.
Handicap creep is usually associated with age, but a lot of these fellows, in their fifties and sixties are retaining their handicap.
But, what convinced me, was an incident at Garden City Golf Club.
I was in a member-member tournament against two mid teen handicap players. We were 1 up playing # 16. One of our opponents hit a good drive but it ended up in the left fairway bunker about 160-170 yards from the green. He walked into the bunker, which has a good lip, with a wood (metal).
I turned to my partner and stated that we would probably go 2 up. Then he hit this wood(metal) 2 feet from the hole, and made 3. On the 17th, a par 5, he hit the green in two, made 3. They parred the last hole, and we were done.
That couldn't have happened pre high tech.
And, it was a sign to me that high tech wasn't just helping the touring pro or scratch golfer, but every level of golfer.
I also have to confess that I have enjoyed the benefits provided by metal drivers and three woods with their longer, lighter graphite shafts. And, I'm not about to return to my Toney Penna woods and balata balls.
