I don't see the introduction of dimple patterns designed to reduce drag, as a viable proposition. It's this one of the areas where manufacturers spend so much on research? This is what makes one manufacturers' ball better than another's. It's what drives the competition, generates business and revenues. The game needs ball research. I believe the simplest way to tackle this issue is for the R&A/USGA to increase the minimum weight of the ball. Manufacturers could continue to spend millions of developing the outer cores and cover of the ball.

Yes, the majority of golfers find the game challenging enough and feel that the ball issue is not relevant to their own game. I myself have not noticed much of a difference in my game. I may hit the ball a bit further, but I still score as I did 20 years ago. But it can affect you indirectly. As someone who appreciates golf course architecture, you will be familiar with many classic design courses that have been altered so that they are able to "defend" their par. We all wish to play "genuine" McKenzie, Raynor, Ross, Colt etc. courses, but it's becoming less and less a possibility these days. Their creations are being slowly (or very quickly in many cases) destroyed.
I would accept that professional golfers have improved over the years. They are now fitter, stronger and can now be considered athletes. But give them a persimmon driver and an old balata and you will then see what a difference the current equipment makes. They have benefited greatly from the improvements in ball and equipment. Amateurs have also benefited, but not to the same extent as the professionals, and this is probably due to fitness etc. A new ball would affect everyone, but I don't think amateurs would see a huge difference.
Tom/Dan:
A gradual change is the only way, but you're not going to see a situation where both balls (if a new ball is the solution) balls are played, as was the case with the large (US) and small (GB) balls. The gradual change that is needed is in the hearts and minds of manufacturers, R&A/USGA, amateurs and professionals, and architects. I don't mind if it takes 10 years, but a decision needs to be made now.
